I don't have a 1/4 inch foot for my FW so I do what I have done in the past and used a strip of painters blue tape to measure off a 1/4 inch. You can imagine my surprise when I finished sewing with the FW and was cleaning it and oiling it to put away for a while so I could use another one of my many machines, I pulled off the painters tape and some of the gold decals came off. Has anyone ever had this happen before. I think I can still use this method but I just must remember not to let the tape go down as far as the gold decals. It is not really noticeable but these decals were in perfect condition.
