Somebody posted a comment asking how I make the caps, and I accidentally deleted it (somehow it got into my spam box; I thought I clicked approved, but it’s gone!). Anyway, I use a commercial pattern to make the cap, doing the CQ before putting the cap together. I’ve also taken caps apart and made a pattern from them. I line them with some kind of fun, coordinating fabric, so they’re usually reversible. I did a hat tutorial a long time ago, so will dig that out and reload it.
Update: The hat tutorial is added! See links to left, under “Crazy Quilting”.
