I can vouch for J Hittle......who is a family owned business.
I buy rotary cutter blades and share them with friends. I also buy pins, and have the special light (attached to my quilting frame) and other products. Good people to do business with.
He will often run a special where you can buy one (1) rotary cutter blade for 1 cent, when you order other things. Check out his ads. He has items for all types of sewing.
