Review on Simthread 27 Spools Trilobal Polyester Embroidery Machine Thread: 27 Assorted Colors with Prewound Bobbins - Size A/SA156. Perfect for FSL on Brother Janome Pfaff Babylock Singer Husqvaran Bernina and more! by Gelin Battle

Received these pre-wound bobbins yesterday and couldn't wait to try them - my first experience with pre-wound Simthread bobbins and they match in colour. I've used them on Free Lace (FSL) designs where you see both sides of the embroidery and they've been simple and reliable, like my experience with Simthread. I have a PE800. The only reason I didn't give 5 stars is the price. $12.99 for 26 prewound spools isn't a lot if you're on a budget, but the convenience is positive having actually used colored spools a few times.
