I haven't been embroidering much lately, and finally got the time to work on a project that I've put off for far too long. Putting some designs on T-shirts for my school teacher daughter. I looked up instructions for embroidering on T-shirts and followed them. The designs stitched out well, but after washing - total disaster! The shirt fabric is ripping away from the stitching. There was no mention about using a ball point needle, but after the fact, I seem to remember that that was what should be used with knits. The directions said to stiffen the fabric with Terial spray and apply web mesh light to the back. So is the problem not using a ball point needle, the fabric being too stiff to let the needle not pierce the threads, the T-shirts being too wimpy, all of the above or something else? Is there anyway to save these shirts? I am broken hearted.
