A rag quilt could be good. They are easy to make and fun as well. Pillow cases are good too. I made can coosies with my DGD the first time. Then we made pajama pants. She loves to wear them and tell her friends that she made them. A tote bag would be another project. Humbug bags are nice when they advance to a zipper. Ask them what they want to make. They will have ideas, I'm sure.
