The plates fixed the table. They did not fix the floor. Bricks still ended up under the sofa, so we sewed a round mat with a raised edge and a drawstring and tested it on our own living room for a winter. That mat grew up into SlideAway: it opens to 52 inches, and the two handles slide everything back into a basket with a lid.
Then the stuffed animals took over the bed. Every parent knows the pile. It grows at birthdays, at every trip to the grandparents, at every dentist visit that ends with a prize. Nobody wants to throw a single one away.
So we made a bean bag cover with no beans. You fill the Stuff 'n Sit with the plush pile, zip it shut, and your child has a seat. The 90 animal cover suits most bedrooms. The 140 animal cover is for the families whose pile has its own zip code.
Everything we make is tested at home first, ours and our friends'. We wash the covers, then check what happened to the seams and the zipper. We hand the plates to a six year old with a box of bricks. If a thing only works when a parent does it, we go back to the drawing board, because the point is that the kids tidy up.
