I love Floriani thread! I also have Sulky and quite a lot of them. This past Christmas I bought the 100 pk. thread and though costly it averaged to $2.30 a spool which isn't bad considering that the lqs sells it at $4.60 a spool. If I don't have the color that I need from Floriani then I'll I'll use the thread chart I have, with the actual threads not the printed color chart, and match them up with the sulky.
