I noticed when I watched a sewing with nancy episode that her machine ....a BL....has the clear plastic 1/4" foot...instead of the one that " comes" with that machine...so I contacted and was told she uses the little foot. I ordered one for my BL....I hate the one with the machine...on the left side it starts out narrow then angles out wide as it approaches the shank and more than two thicknesses of fabric will get caught...it does not " float" over the fab....the little foot does not have that design flaw and the fabric just keeps moving......for me worth the little investment....
