I prefer Robison Anton thread, I am using polyester more than rayon because of its durability. I bought 27 spools of polyester from discountembroiderysupply.com for $100, free shipping. It's about $3.65 a spool for 1100 yards, which is considerably cheaper than Sulky from Joann's at 4.99 for 250 yards. You really need to look at the size of the spools in relation to the amount of thread you're getting. Even when Sulky is on sale at Joann's, which isn't that often, it's still usually at least $3 for 250 yards. It's good thread, but it's not worth the cost, IMO.
