Wow! Thank you so much for ALL THAT GREAT INFO. I learned a lot and have a lot more to learn about my machine. Funny thing is, I've been sewing for 23 years and only ever changed the foot to a zipper foot. Just the other day I was looking at the various presser foots I have and wonder just what they were for. Thinking I needed to do a google search on each one. Now I feel so naive. My machine is a Brother XR-37. Its old maybe 15 -20 years old but works just fine. I would love to get a newer machine but cant find any reason to replace that which is not broken and serves its purpose just fine.
Thank yall so much for your help! I'll be back for help soon.=)
