maybe you are putting too much pressure on your cutter...if your blades are sharp they should go through with out much pressure. also, try different height's to cut at...i found if i sit to cut it causes shoulder pain, also, i had to walk around the house trying different levels until i found the perfect height for me to stand and cut pain free. i tried the kitchen table...too low, the island...almost right...another table with stools not too bad, went out and bought a new cutting table that folds up and is just right. it is important to have your table the correct height for you to make it ergonomically work for you. also, dont cut a whole quilt at once...breaking up cutting time may help. but i think not putting so much pressure on the cutter and finding the correct height cutting surface will help amazingly well.
