There will be 17 kids in the class plus 3 teachers...I don't have any size for the quilt in mind but I do have a small sewing machine, so it should be kept just larger than a baby quilt...or maybe twin sized. Not sure which.
I have been thinking of making the blocks the kids draw on 8 1/2x8 1/2 or 9 1/2 x 9 1/2... I know most 4 or 5 yr old's like larger spaces to draw on.
As for the class picture, since 3 kids will be transitioning into the class we'll have to take a picture of the entire class. So, I can do many things regarding the picture at that point. If we use a class picture, I'd like the picture to be easy to see from a reasonable distance.
