What a cool pj, Kel. You did great. As for tips, first of all, make sure you use needle for strech material. I prefer using overlocker to sew strech knit. But if you have none, try to use a zigzag stitch instead of straight on your machine. Set the width & tension of the machine, so that it looks almost like a straight stitch. I usually use (width 2 & tension 3). Do a practise run first.A walking foot put on standard sewing machine will help reduce the puckering. But if you don't have any, just go slow & steady. Don't pull the material. Feed it to the machine gently as the machine stitch it. Hope this helps.
They look awesome.Wish I had some tips for you, one of my crafty resolutions this year was to sew more with knits and stretch fabrics, but I hate sewing with them for all the reasons you mentioned.
yeah, vita is right. a serger is best for stretchy jersey material. but the special needle combined with a light zigzag stitch will work as well. i just noticed my sewing machine as an overlock stitch, i wanted to try it out soon, maybe your's has one too?
Thanks so much for stopping by. I love reading your comments - they really warm my heart. So thank you!
