How can I improve seam elongation?
To improve seam elongation, you can increase the stitch rating per cm or inch, increase the bite, reduce the needle/looper tensions on affected seams, or change the type of thread used.
Why don’t I always get the same shade in thread and fabric during cotton garment over-dyeing?
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.
