I am working on the Christmas tree from Pat Sloan right now! I laid it out with my stash of Christmas 2.5 squares but ended up using a holiday jelly roll I have had for a couple of years. The pattern is fast, easy and can be done in 2.5 squares or 5" charms. I will post a photo of a finish in a day or two.
Here is the link to both mini charm and 5" charm trees pattern.
