My only suggestion would be to get a Buggy Barn pattern for her to create. They are forgiving in that basically all you have to be able to do is sew a straight seam. The sizes of the seams aren't as important. If you sew some seams which are more than a quarter inch, then your blocks will all just be smaller but still ok. The patterns are for wonky things like stars, hearts, and baskets. They're wonky, but still very pretty, and totally fun to make. The fabrics are stacked up and then the pattern is rotary cut through the entire stack of fabrics (so there are no seam allowances on the pieces---thus the wonky end result). Then the stacked pieces are shuffled to make each layer into a block ready to sew. After the block is sewn the sides are not straight (since there were no seam allowances in the first place), and the blocks are just trimmed all to the same size. So easy!
