In reply to European leather I like triple feed, I have this on my Juki DNU1541, and I have ground off most of the teeth on one of my Juki feet so as not to mark veg tan...the needle drags the leather through very well.....I like the Juki, not so much power an on my 133k but a very versatile machine and a pretty good all rounder. One trick I sometimes use is to put a sheet on paper on top of the veg tan to reduce any scope for marking the leather.
In reply to SanteFeMarie - I would be interested to hear other peoples thoughts, but I just manage by tying thread ends and singe with a lighter (bonded nylon) when I cannot turn the work around.
