Oh, I have no problem taking Miss Elna apart and cleaning her. I used to pay to have it done every year then the two repairmen that knew what they were doing retired. I have the number for one of them. He does exclusively Elnas in his home, but I haven't needed to use it. Mine is the light blue one.
H-m-m-m. Maybe I should try the hair dryer on the ZZ gear on the Stylist. Her straight stitch is fine, but the ZZ clunks. I wonder if it has anything to do with the broken plastic washer?
