This is block 8 in Susan’s Stars and Pinwheels QAL called Christmas Pinwheel Star.

Since I’m making a small project each month with the featured block, I decided to use this block in a cover for a lumbar cushion. Because the cushion is curved, it’s difficult to cover and I used a lined 30 inch x 10-½ inch panel with Velcro on either end to fit over the center of the cushion.
I reduced the size of the pattern to 8-½ inches unfinished (2.5 and 3.5 inch squares) and added borders plus some longer pieces for the cover to join in the back.
I thought this was a very pretty block and it was easy to put together with half-square triangles.

What a great idea that is, Lillian! It certainly dresses up the cushion. I love your colors and the added borders.
Wow – I’ve seen lots of lumbar cushions – but none were ever as pretty as your custom covered one! What a great idea. I’m sure there are many people who would love it. Mine was so gray and ugly I was happy to leave it at the office when I left. 🙂
It’s beautiful as ever and lovely to put your block to good use. I’m so pleased to catch up on what you’re making. ☺
