I found that the table I was cutting on was sagging in the middle, which made all my cuts just a little off. The plastic table ended up with 3/4" piece of plywood over it to solve that problem. I have also found that if there is more then one fold, my cut pieces can have those lovely dog legs. I always wash my fabrics before I use them (I don't like the chemicals that are used in the warehouses on them), hang the fabric on the clothesline to dry and spray the fabric liberally with starch while the fabric is still wet. I always press the fabric before I cut it. Feline Fanatic is quite right in her answer. Hope you figure out what has caused this reversal of skills!!
