Melissa & Doug, watch out! A few sheets of felt, found at a fabric or craft store, can become a Make Your Own Pizza Kit or Make Your Own Taco Kit for your own child or as a gift for someone else.
My favorite part of this activity, as emphasized by its author, my friend Jackie, in the post on her own site, is that sloppy cutting is completely appropriate.

If this project is too easy and forgiving for you, try this more complicated tutorial for felt ice cream or felt sandwich (with sewing!). If it was too much material and cutting, buy a kit!
