I found a disappearing pinwheel block I’d never seen before on YouTube. It’s a basket! I made one and followed their suggestion to take a pinwheel from another block so that the “flower” on the basket would be a different color.
Since I’m on a basket theme, here’s an improvisational basket block I made recently. Here it is with the bias handle pinned on, ready to be stitched (by machine). It’s important to iron it after pinning it so that the fabric relaxes into the curved shape.
Here it is finished. In this photo it looks like ombre fabric, which would have been a great idea, but it’s not. I made a quilt with several baskets, a few years ago. You can see it here.
