Just got in a bag of samples from Madeira...and its not the first...too bad Melco didn't have such good attitude...but I can't tell the difference between L and M bobbin size! If I got both sizes in the sample pack, they look like they'd fit my bobbin holders. Only difference I read is the length of the bobbin...L is 132 yards, M is 235 yards. Will they fit our regular bobbin holders? Would certainly save a lot of changes! Roland R.
