Ok Crossstitcher,
I really did write a reply... LOL lost it some how.
The disc in that Elna is an 'Elna single discs' There are some that look like two discs stacked together and they do fancy stitches. They are called 'Elna double discs'. Both should fit your machine. I have some that are like the single disc but they don't have the rim around the top, they are about a hair shorter and are the only ones that work in that beige Elna. I wonder if some of that rim could be shaved off to make them fit her. The 'top hat' discs are for the Singer slant-o-matics and do not interchange.
