I am entering this into the wood working challenge so please vote for it!
Step 1: Materials and Tools
-Flannel (You want 100% cotton flannel. This is a very cheap fabric, I got mine for $1 a yard, and just ended up buying the rest of the bolt for $12.33. I ended up with a lot left over so I would estimate you could easily make three wheels with 8-10 yards.)
-9x9 scrap of plywood (The measurement of the wood merely dictates the diameter of your wheel. If you want a larger wheel, use a larger square, smaller, use a smaller one. )
-3 Medium-Large Screws (Machine screws, not drywall)
-6 Washers, 2 small, 2 large
-Fabric Scissors (You will notice that mine are not fabric scissors, and I deeply regret it. If you have them use them, but regular scissors will work.)
