Ok so I am workin on this cute quilt bag and the instructions call for ruffles which really add a nice finish look for the bag. I have my pieces prepared and was told to increase the tension to create a stich that will produce a ruffled look, I tried that and its not working. Using a needle and thread takes too long, but another tutorial said to change stitch to longest stich! So my question is when you change your machine to the longest stich does that mean to change the tension? I think my machine is a bro LS 2125 or 2150? It is the basic brothers.
