I was put in charge of making a Valentine's Day wreath for our office door. I
For the base I used a sheet of bristol board. I cut a 10" circle. I made the base 1 1/4". I made a bunch of pink, red and heart printed yo-yos and glued them on with tacky glue. I then added buttons and trims that I had lying around. Easy, quick and a great way to use up some fabric scraps and odds and ends trims.
After finishing and hanging it up I wish I had made it heart shaped. But it was simple and easy and brightens up the door.
Side note: I treated myself to a few skeins of Debbie Stoller's Full O' Sheep yarn and it is lovely. It's great to knit with and is working up really soft. And the colors are fab.
