I am going to make a pair of boots for your doll like UGGS or bear paw using felt, craft foam, a needle, and thread, paper, and pencil for the pattern and glue. I start by taking the paper and pencil, and I make a rough sketch of what the boot look like. It would take four parts, so I sketch the pattern down below starting with the bottom of the shoe, the back, the top and the front. I developed this pattern trough trial and error, going back and re-adjusting until it worked. I’ve included a small seam allowance,
