i've been quilting a long time (first quilt in 1976) and have never been happy with a machine binding---they never turn out as nice as a hand stitched binding (mine anyway) to me it seems like putting so much work into a quilt i simply ruin it if i try to *cut corners* and do a machine binding. I've watched videos and tried lots of peoples (new-improved way) but in the end i always regret having tried it again- so..all i can offer is:
if you really want to do your bindings by machine- there are good tutorials & videos available---watch them & practice- after a while you may figure out what works for you that you are happy with- me, i will stick with the (old fashioned way)
