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.

### ⭐⭐⭐⭐⭐ Flawless Stitch-Out with Superior Quality Metallic Thread
*by S***Q on February 10, 2022*

If you want to add some pizazz and sparkle to your embroidery projects, then you should definitely put a set of Simthread's 21 Best Colors Metallic Thread in your Amazon shopping cart right now. The price is right and the quality is fantastic. There was no tangline or shredding on any of my projects, and I was super impressed. If you're one of those individuals who has avoided using metallic thread in your machine, this is an opportunity to experience the thrill of flawless, hassle-free stitching with this carefully curated selection of colors. The thread performed perfectly on both light-to-medium weight fabric as well as a heavier-weight brushed denim (see photos and video above). This is an excellent value for sewists of all skill levels. You can't beat the price, and if you've been a customer of Simthread's regular embroidery thread, you know that you can count on their good quality and customer service. Highly recommended!
