I don't know if you saw my posts about teaching my grandkids to sew this weekend. My DGD is going on 7 and my DGS just turned 8. We did start with charm squares. I marked the 1/4" seam line with a Frixon pen so they could follow a line. First I got her used to the process of putting the fabric in, presser foot down, sew to the end, presser foot up, turn the wheel to release. She picked up on the process quickly. Her brother wanted to do it also. I had bought her a Hello Kitty sewing machine made by Janome, and it was exactly like one I found at Hancock about a year ago for $89. So they sat side by side sewing their charm squares together, it was so cute. They really got the process down very well.

What about a turnover quilt with jellyroll borders around the two sides of the turnover? She could do the pink and black thing. I think MSQC has a sample of this using the black and yellow line (Lemon Tree) somewhere on the website or Facebook posts. And the jelly roll quilts are so fun to make and a little deviation in seam width won't throw the whole thing into a disaster. And I made lots of quilts using 8-1/2" squares made into half square triangles to make any number of designs with the triangles. If you look at my albums, you can see some samples. Good luck with it.
