How can I improve seam elongation?
To improve seam elongation it is possible to increase the stitch rating per cm or inch, increase the bite, reduce the needle / looper tensions on affected seams or change thread types used.
During cotton garment over dyeing, why don’t I always get the same shade in thread and fabric?
The dye uptake depends on many parameters such as cotton type, quality, finish etc. and any difference in these parameters between the fabric and thread will result in shade difference.
