There are quite a few online quilt/fabric sites, these are a couple that I've used in the past and was very impressed with their price and quality of their fabrics, and also their service, these are Thousands of Bolts and Jhittle. The other places that can be great finds are yard sales, thrift stores, etc. The rotary cutter does take a little practice, but personally, I find that the 45mm cutter is a whole lot easier for me, plus, I can get the blades a whole lot cheaper than the 60 mm. I also want to welcome you to the wonderful world of quilting.
