I loved the colors of the charm pack, sold here on Craftsy, so I bought 2! This quilt takes just one of the packs, and uses all 100 squares in it. I decided to do a disappearing 9-patch, and I love the scrappy look. The colors are so happy, hence the name of the quilt, and then I thought it would be fun and silly to stitch happy faces all around... of course, there is always one [or two] not so happy faces in the crowd, can you spot them? LOL I'm going to play a game on FB - whoever catches the one mistake on this quilt, gets to keep it... let's see if they can spot it, can you? It's a piecing mistake, but I decided to leave it in, just because.
