I'm making myself a panel skirt with the most amazing light grey fabric. The problem is that this fabric is a little stretchy and heavy and the seams will need to be more than a straight stitch on the inside so the seams aren't visible on the outside. I've been looking at different types of seams trying to find one that will be 100% on the inside but so far everything is inside and outside (ie the type on jeans- felled something or other I think) I did look at a french seam but perhaps it was a bad tutorial since it looked like there was thread visible on the outside? Any suggestions??
