I put together some options and really liked the orange, deep aqua and magenta with the bright yellow right away so the only choices I had to make was to select a green and purple. I played around a bit and came up with......
.... the Chambray (a fabric favorite). In went the purple/turquoise and the meadow grass which had a touch of purple and orange.
Here's my completed "made" fabric. I added more of the yellow to brighten the block a bit and all the fabrics next to the yellow really stand out.
I like how it turned out. While I'm still not crazy about yellow, I will be adding some to my stash and incorporating it into future projects.
