(should have said bobbin washers....duh)
Have any of you used these specifically in a class 66 machine which has a drop in bobbin and if so were the results good. If you do use a 66 to free motion on would you mind sharing the particular foot you use.
The reason I ask is because I have a sewing class room equipped with mainly 66's and some 99's. I would like the gals to practice free motion and it would be easier for me to use the 66 machines with them.
I usually free motion on my 15-91 and I have an old industrial singer I use for really big stuff but to teach I would like to use the 66's since they are set up so close together.
Thanks in advance, Gwen
