Sunday sketch #305

After three weeks of curves, it’s back to angles and straight lines for this Sunday’s sketch.

Using only the blocks with coloured outlines could make the design feel a bit cluttered, but the consistency of the white centres helps to relieve the busy-ness (a bit).

And, of course, the blocks can be rotated to create star shapes behind that lattice of horizontal and vertical borders.

Paring back the palette helps to focus the eye on the different angles at play – horizontal, vertical and diagonal lines criss-crossing the design.

And to take the design in another direction entirely, I coloured adjacent blocks in a similar way, to create stacked bricks with different internal motifs.

I prefer the first few (brightly coloured) versions, but I like sharing the others in case it sparks a fellow quilter’s creativity!

These designs can be made using half-rectangle triangles, 2:1 rectangles, and longer rectangles or strips for the block’s borders. A very straightforward design that could be made easily into an actual quilt!



Sunday sketch #298

The whole point of my Sunday sketch series is to show quilt designs, so there’s an unspoken rule (at least in my head) that all the designs should be makeable. I’ve said before that the skills required to make a particular sketch into a quilt tend to match my own sewing skills at the time I made the sketch. In other words, my ‘design’ brain is pretty aligned with my ‘making’ brain. That’s why I didn’t really design with curves until I could sew a curve, and I haven’t designed with (m)any Y-seams because I haven’t yet sewn a Y-seam. (Not that anything’s stopping me! I just haven’t got around to it yet.)

Anyway, all this is to say that occasionally, there are exceptions. I’m pretty sure that this week’s Sunday sketch is makeable – I think you could use paper piecing, start with a few partial seams, and then sew all the pieces in each block a clockwise manner around the central square, finishing off by completing the original partial seams.

I’m not excited enough by this design to bother checking whether that construction method is indeed possible (or desirable). But I can still share all the iterations!

This Sunday sketch is a block-based design using multiple half-rectangle triangles. They’re joined to each other primarily by their diagonal angles rather than their short or long edges. There are three ‘sets’ of HRTs within each block; in the top design, two of the sets are in colour and one is in white. Here’s each set coloured differently:

That can get a bit busy, so I feel like it helps to have one colour that ties all the blocks together (in this case, white) and other colours that appear more than once.

The design can also use a much simpler palette too.

Or you could use an expanded palette but stick to one colour per block (as in the first version). Here it is again, using a white background instead of the dark blue.

I’d use paper piecing to make these blocks, because I feel like the potential for wonkiness would otherwise be too high – sewing a bunch of triangles along their bias edges would be a recipe for disaster (at least for me). I’ve never tried paper piecing with partial seams though. Is that possible? I feel like it should be. It might be easier with freezer paper piecing than with traditional paper piecing. Hmm… now I want to try it!


Finished quilt: Sketch

This is Sketch, one of my absolute favourite quilts of all time. It’s a hand-drawn sketch recreated as a quilt, made using freezer-paper piecing with striped fabric.

Sketch is based on a modified version of Sunday sketch #181, which I posted on 15 December 2019. That design, which I drew with a gel pen on a Rhodia dot pad, looked like this:

Geometriquilt: Sunday sketch #181

In the blog post at the time, I wrote:

You can see from the scale of the background dots and my fill lines just how small this design was on the page of my Rhodia dot pad – only a few centimetres across! I love a good triangle, and I just started placing them on the page, following only one rule: each triangle I added had to touch an adjacent triangle, but only at a tip (no back-to-back edges allowed). I stopped when I was happy with the random arrangement.

Those of you who know how much I like symmetry and order can probably see that despite the ‘improv’ nature of this design, it’s still fairly well balanced in terms of positive vs negative space, and the number of shapes in each quadrant. Even when I’m not trying to be ‘ordered’, it happens 🙂


I thought that the design would look great as a large quilt, but I didn’t spend much time thinking about how that might be possible – I guess I just assumed I’d piece large shapes in a solid colour. I never got around to doing it, and moved on to other designs.

I’m not sure when it first happened, but my quilty friend Tamara Stunnell – who I met through the Melbourne Modern Quilt Guild – suggested that I make the sketch into a quilt using striped fabric to represent my sketching lines. Ooohhhh. Brilliant idea. Genius. I knew it would be amazing. But also way too hard. I let it slide.

Then she said it again. And probably again. And each time I’d say “Great idea!”, then change the subject, cos I honestly had no idea how I’d do it. I’d need a striped fabric with the same imperfections as my hand-drawn pen lines. I’d need to create paper-piecing templates for every single triangle, and figure out how to add the thin black outline to every shape (in the exact same width as the lines in the fabric, just like in my sketch). I’d need to make sure the striped fabric lined up on every single piece, so that the lines all followed the same direction across the quilt – just like my pen lines do when I’m sketching on a page. I’d have to make sure that a black stripe never ended up in the corner of a shape, right up against the shape’s black outline, or it would make it look too dark and draw the eye unnaturally towards it. I’d need to figure out how to sew all the shapes together, probably using some partial seams. The points of the triangles would have to meet perfectly. And I’d have to do it all with a large white background, which would show up every stray black thread. Are you kidding me?!?! No way. It’ll never happen!

And then we were in our local quilt shop – GJ’s Discount Fabrics – one day, and there it was: the perfect striped fabric. The black stripe from the Dot and Stripe Delights range from Robert Kaufman. Stripes that look hand-drawn. Fairly regular, not perfect. A few flecks that look like ink here and there. And the stripes are around 1/4″, meaning that the outline of each shape could also be 1/4″ wide. “You should make that quilt,” Tamara said. Arrghhh! She was right, of course. I bought yardage.

So, with no deadline in mind, I started planning the quilt. I revised the sketch, making slight changes to avoid some parts I hadn’t loved in the original. But I kept the design mostly the same. Here’s the updated version:

I counted up all the shapes and made freezer paper templates for paper piecing. I marked on each one which direction the stripes should point, to make sure they were all parallel in the finished quilt (just like they are in the sketch). And then I got to work making all the pieces. Some pieces are unique, while others – like the 2:1 half-rectangle triangle – appear a few times.

Once all the triangle units were done, I put them together into the quilt top. Only one partial seam was required for assembly. I was really happy with how it looked, but hardly took any photos cos I was terrified of mucking up a mostly white quilt!

I sent Sketch to Valerie Cooper of Sweet Gum Quilting for longarm quilting. After talking through various quilting options, we settled on a grid design in white thread to represent the graph paper I use for sketching. Valerie offset the grid so that the vertical and horizontal quilting lines (in white thread) avoided the vertical and horizontal outlines of the triangles (in black fabric).

I finished the quilt with a facing, so it was nice and flat like a sheet of paper. Here are the sketch and the quilt side by side. I honestly couldn’t be happier with how this quilt turned out.


So this quilt represents a few things for me. First and foremost, the importance of supportive friends who know when to nudge you beyond your comfort zone. Also the joy of making for the sake of it, with no purpose in mind other than to tackle a challenge. And finally, the evolution of my design and quilt-making skills. When I first posted this Sunday sketch in 2019, I wasn’t ready (and possibly not able) to make this quilt. But two years later, my skills had improved to the point where it was possible. I love seeing tangible signs of how my quilt-making has developed over the years.

Sketch was juried into QuiltCon 2022, and will hang at the show in Phoenix, Arizona. If you happen to spot it there, send me a pic or tag me on Instagram! I’d love to see it.
