I was given a Tandy lace maker. The couple of time I have tried to use it it takes about 10 mins to get it to start to cut the lace but by the time I get a goos start it has made my hole about three times what the original size was. I have been using scrap upholstry leather I get from work. Should I use heavier leather? Can I use veg tan? Any help would be appericated.
