Step 1: What You Need
Other than that, the list of supplies is very short:
- At least one large t-shirt* you are willing to bid farewell (One men's large to x-large t-shirt makes one potholder, so how many you need really depends on what you are making)
- Large knitting needles, at least US size 13, 9.0mm (I'm using US size 19, 15mm)
* T-shirt type note: Best to use are ones with no or at least not 'heavy' graphics and ones that have no seams down the side (the body of the fabric is a seamless tube).
