Review: Pretty colors, no breakage - Love Simthread! Great price for all these pretty colors. No trouble with thread breakage. They work well.
Review: Very Nice Thread, So Shiny - I love the colors, they are so vibrant and look much shinier in person than they do on my pictures. I sewed with my Brother PR650 six needle. I used a 90/14 Top Stitch needle, which has a longer eye and wider groove and sewed at 500 spm. I didn't change my tension or use the thread nets. I tried to use a thread net but it was too tight to let my thread come off the spool. (could be I didn't put it on right) When doing the first design of the shoe I used my regular embroidery needle and had a couple of breaks. After changing to the Top Stitch needle, as recommended, I only had one break. I couldn't wait to do some free standing lace earrings. They sewed out beautifully, I used earring patterns from Sonia Showalter Designs. They look so much better than the ones I have done with regular embroidery thread. I will be using Simthread's Metallic Thread from now on for my FSL earrings. It did not tangle, nest or shred which is a big plus. Looking forward to making cards with my metallic thread. I'm happy with my order and highly recommend Simthread Metallic Embroidery Thread.
