Singer low shank buttonholers will fit your machines.You will need the one in the green case. Either the older black model or the biege model will fit. They were considered as extras and had to be purchased separately. I can often pick them up for less than $10 in my local 2nd hand shop. My last one was $3 and had extra cams. You should be able to buy a walking foot, 1/4' foot or a foot to do free motion quilting at your local sewing machine shop. I bought all of these for my 201 Singer, walking foot was $22.99, 1/4" foot was $5.99 and the FM foot was $8.99 and I had more than one to choose from.The generic ones made for low shank machines will all fit.
