My daughter said that my grandson, who is just over 3 mos, is starting to want to hold something to snuggle with. She asked if I could make something small for him to Snuggle with. What do you think would be a good size. I have started with a soft flannel, making it a raggie, and my blocks are 6 1/2" unfinished. I will use a 1/2" seam and then rag them. If I go with 3 x 4 setting it will be approximately 16 1/2" x 21". Do you think that is a good size??? Should I make it a 4 x4 setting to be 21" square or go bigger with a 4 x 5 setting to be 21" x 26"ish???
