Looks can be intimidating but it so easy as 123.
Bought my supplies from Joann’s fabric store for half the price using the 50% coupons that cost me 1.50 plus tax. It has vast of different sizes and in quantities, and I use large size and use an excess fabric from my one of pajamas projects for my son. Instructions and directions is on the back of the case and it easy as covering the top to any fabrics you like. It comes with a tool that holds the cap in place when you encapsulate it with fabric.
