This Boo Boo bag is made entirely in the hoop, and requires no additional sewing!!! It comes with the words Boo Boo Bag, and the lip prints. It comes in 3 sizes, 4x4, 5x7, and 6x9. 6x9 & 5x7 hoop shown. All you need is to fill a baggy with crushed ice, and stick it in. I usually do these in flannel so they are soft on the boo boo. The small boo boo bag is the perfect size for a sandwich baggy. Crushed ice is perfect!! We keep ours in the freezer already filled, and the kids know just where to find it. When someone gets a boo boo, they go running for it. They feel special to get the boo boo bag for the ouchie. The best part is that you can throw it in the washing machine and it is ready to go again... Notice I had to make one for Ga Ga, as the kids needed one for her house too. :)
