Causes of Puckered Seams
Puckered threads across seams are due to a blunt needle or too large a needle. Stitches are too short for synthetic and easy care fabrics. Using a plate with a wide needle hole may cause straight seams to pucker. Upper thread and bobbin threads are of a different size and/or type.
Why are my seams wavy?
The weight of the fabric hanging down is often enough to stretch it and cause those wavy seams we talked about before. Steam – If you have already sewn your seam and it turned out a little wavy, steaming the seam can often help smooth it out. Steaming is different than ironing. Do not move the iron back and forth.
How do you sew stretchy fabric without puckering?
Ensure you opt for the right size of needle for your fabric. Use stitches that will hold the stretch of the fabric – the stitches need to stretch with the fabric, so they don’t pucker and break. If you must sew with a straight stitch, then hold the material taut, but don’t pull it.
