I've had great results from June Tailors from Walmarts in quilting and embroidery. It cost a lot less than the others, doesn't gum up my needle and holds just as well. Yes, I got the 505 and tried it but it didn't hold up as well. Now, I will admit that maybe I didn't put enough spary on it because I know alot who love 505 so I will say that the blue can from Walmarts is just as good and leaves green in my pocket.
