Oh! I thought of one more. It was a panel with a castle on it. The panel itself was pretty, but if you looked at it closely, one of the castle towers looked like a ... (ahem!) ... "male appendage"!
Unfortunately I didn't notice the resemblance until after I'd finished the quilt. Edit: The panel is called Avlyn Goose Girl Castle. Go look it up on eBay if you want to see a photo! LOL!
