Sewing swim/dancewear fabric
I am making a unicorn costume for my granddaughter. The one I am copying looks like this type of fabric. I have it already cut out but I was trying to use my serger to finish the seams and it does not serge very easily. Are there any special tips I should know for sewing this type of fabric. It is very flowy and stretches both ways. I don't think the cut edges will unravel but I like to finish my garments on the inside.
I am using ball point needles. Whatelse should I know. Thanks.
