Sunday sketch #190

Remember in last week’s post, I mentioned liking a star shape that emerged from the quarter-square triangle design? Well, I decided to take that star, which is based on a 3×3 grid, and use it in its own design.

I separated the stars with some thin sashing, using small squares to fill in the negative space where the horizontal and vertical sashing meets.

Of course, you could fill in that middle square too.

But I also like the idea of filling the empty square with a different colour, to mix things up a bit. This is my favourite version. This is also a bit of a quirky colour palette for me, but I really like it.


I think the design works without the sashing, but only when the blocks are coloured in a way that distinguishes each one from its neighbours… otherwise I think it looks too busy.

The design works in a more limited colour palette, too. Here I’ve used 2 colours plus the background, and just alternated the central 4 half-square triangles with the outside 4 quarter-square triangles to add a bit of interest.


And if you have the same reservations I do about using white/light backgrounds for quilts, you can use a dark background instead.

This design could be made into a quilt using half-square triangles, squares and quarter-square triangles. Plus a bit of sashing – or not!


Sunday sketch #189

Here’s another quarter-square triangle design, following on from Sunday sketches #187 and #188. This one’s coloured slightly differently, which essentially changes most of the QSTs to HSTs (half-square triangles).

And the obligatory reverse colourway…

I really like that centre star – the one created by the middle 9 squares. Look out for that motif in another design in the future!

In the meantime, here’s another idea for colouring this design: starting off dark at the outside, and moving into a glowing centre.

That’s just a gradation of greys –  a ‘greydation’ haha – but I think it would work just as well in a rainbow colourway. Bright yellow or white in the middle would look great!

This quilt design could be translated into a pattern using mostly HSTs and some QSTs. A simple yet sophisticated design.


Sunday sketch #188

As promised, more quarter-square triangles this week.

This is obviously a really simple design that keeps half of the quarter-square triangle unit as a solid colour, using three colours per unit instead of four (with one of the colours being white in this version). Then the units are grouped into 3×3 blocks. This combination of colouring and arrangement limits the busy-ness of the QSTs and helps to maintain some continuity between the units and blocks.

The design also works in a more limited palette.

This design could be made into an actual quilt using only quarter-square triangles.

When you make QSTs, you make two at a time, and those two are mirror images of one another. If you’re only using two colours, you’d hardly notice, because you simply rotate them and they look the same. But if you’re using more than two colours, it can be a pain if you have a design in which all QSTs need to look the same (because half of them will look like mirror images). In the top design, I’ve accounted for that by using both groups of blocks. For each QST colour combination, there are two blocks; both have the big white triangle at the bottom, but the two colours on top switch sides. I didn’t do that in the bottom design – I just coloured that one quickly, without much thought – but it could be rearranged slightly to make sure that there’s less wastage. Then again, you could always set aside unused blocks and make them into another quilt!
