I've looked everywhere for that presser foot... Hancocks has never heard of it, Joann's doesn't carry anything like that that fits on my (very standard) Singer machine. Best I've found is $15 shipped on Ebay. $4 sound much better to me . If anyone has a source please post or PM me. Thnx
You don't need a presser foot. I have the $80 Wal-Mart Singer machine and as long as you take your time and put a leather needle on your machine it will be ok. My girlfriend's 1/8 thick real leather belt popped apart. I rethreaded the belt through the buckle and doubled the belt back onto itself, then sewed it together. Just take your time and don't rush it.
So I started sewing with my metal foot, and for the first 12 in. the stitching was uniform but after that the vinyl began to catch and the stitches ran together:facepalm. I was able to get it to work reasonably well by yanking the material through the back of the machine to help feed it but the stitching was still a bit erratic. Luckily I found a can of Silicon Spray Lube in my cabinet that did the trick beautifully! I just sprayed a little on some scrap fabric and wiped it over the vinyl. Worked like a charm.
Sorry if this is not posted in the correct place, but here are some other measures which, IMHO, are more accurate than the ones posted. The cut corners are an approximate measure, some are a bit lower, some others are a bit wider but never more than 1/16" plus:
