? For Long Arm owners re: needles
Do you use a size 18 needle most of the time or do you have a preferred size depending on the fabric? Do you use a size 16 and if so on what type fabric? I'm getting ready to do my first batik and I'm concerned because my machine co-owner is doing a batik now and is having problems with the quality of the stitches on some of the fabrics (she's using a size 18 needle).
Also how often do you change your needle ?
