I have hem foot attachments of varying widths in the parts that came with my old Universal sewing machine (clone of Singer Model 15, I think)

I have played with said attachments, with no success.

Can the Rev, or other of you sewing mavens, give me some guide lines and tips?

I'm kind of thinking if you combined justJeffs no pins technique with the hem foot It might work. (i.e. hold fabric infront and behind of the foot as feeding through)

Any and all advice gratefully accepted.
