I whipped up a quick I Spy quilt for a baby gift this past Friday night. The shower was Saturday AM (yes--very last minute). I picked up a pack of bright charm squares at Walmart. I keep a stack of 4-1/2" squares of I Spy prints at the ready. I picked out ones that matched the colors in the charm pack. I thought it turned out nicely in spite of being thrown together quickly.
I backed it with Minkee and did not put batting in. That makes it nice for snuggling.
