I practiced blind stitch on the hem of pants but it PUCKERED! I don't want saree to PUCKER. Then I realized that I used nylon embriodery thread to do blind stitch on pants. My Question: What thread to use to attach fall. Google search says 1. Same color thread 2. "Invisible thread" When I search "Invisible thread" on Amazon I get results for Nylon thread. https://www.amazon.com/s?k=invisible+thread&ref=nb_sb_noss But I thought Nylon thread is no good This one has size of thread, .004 it seems https://www.amazon.com/YLI-Corporation-Wonder-Invisible-Thread/dp/B00A2GSI3I/ This thread says it is used for arts and crafts, nothing about blind stitch! https://www.amazon.com/SINGER-260-Invisible-Thread-135-Yard/dp/B000IGEBSS/ Soon lockdown will be over and we'll be going out. I wish to attach fall to saree without PUCKERING. Please help!
