CONGRATULATIONS ON YOUR NEW LONGARM...regarding your breakage on Golden threads...Ive never used theirs, but I have used Connecting threads Essential Pro, with great success, recently I started using Glide thread from Fil-tec and love it, its high sheen, whereas the Essential Pro is a matte. Many of the thread companies offers trial sizes. Dont forget...dont be afraid to adjust your tension. Superior Threads has videos showing their threads on just about every longarm on the market and they have great tips as well. Good luck, have fun!!
