I am still working my way slowly through the saga of my daughter's curtains, and am trying to hand stitch the bottom corners of the hem. I normally only use polyester thread, but the fabric came (from Just Fabrics) with reels of Gutermann cotton thread. I am assuming all you Dark ladies use cotton thread for your quilts and wondered if you have come across the same problem I have. The thread is fine in the machine but, if I pull off a length to thread a needle, it comes off in ringlets. Before I've even got the needle into the fabric it's springing back on itself and tying itself in knots! It's driving me potty! I've tried running it through candlewax and soap but nothing seems to help. Can you?!
