Review on Vibrant 40-Spool Polyester Embroidery Thread Set For Brother, Janome, Singer, And More - 500M Spools, 40Wt - 4 Sets Available At Threadart! by Rob Bishop

I have used two spools so far and they kept breaking. Not because of the quality but the design of the spool. I think the head of the spool is a little low which causes the threading on the top to fall off, get tangled and break on yhe machine when it cant be feed. I'm hoping this doesnt happen to all of most of them. the spools are also smaller thatln the others I have used. The sticker with the number on top it supposed to gace a slit for the stick to go thru but it tends to stick on the pole and gum it up and then cause the thread to stick and break again. Just get rid of the sticker entirely before use.
