I starch my fabric before cutting with the Go. It helps with the smaller size cuts. You can align fabric to be cut on grain. I cut a lot of scraps and put the fabric anyway it will fit and never have a stretching problem that caused any distortion. If you are having static cling with the mat, spray with Static Guard or wipe the mat with a dryer sheet. The more I used the Go the better cutting job I got. Now I can throw some fabric on the die and roll it through and never think about it. There are lots of youtube videos that show the tricks and tips.
