My Viking Epic1 came with the walking foot with options to buy more feet for decorative stitching. I bought those I thought I could use as some you could use for the same thing so why buy them all? So far I haven't done anything with them as I most times stitch my binding using my little Brother machine sitting on the cutting table. It's lighter weight so reason for using that machine. I'll have to check the walking foot that came with it to see what size hole it has as I've got 3 quilts needing their binding to be stitched on.
