I have done straight line quilting on several Carpenter Star quilts (which is my favourite pattern) & they have turned out
great. I feel (IMHO) that sometimes, depending on the quilt pattern, meandering or other intricate designs really take away from the beautiful quilt pattern, that's just my opinion. You can do lots of straight line designs & it just takes some thought at which one will enhance the pattern. Don't be afraid to try it.
