Hello I was wondering if anyone can point me in the right direction. we need to do a leather corner 90 degree stitch on items similar to the pictures I have attached. we do not want to do this by hand but would prefer a machine without breaking the bank. I was told the Campbell would do this but heard the landis 12., Can anyone tell me the best machine for this ? I was told it can be done with a singer 97-10 or a 29k60. im kind of stuck here any help would be very well appreciated. thank you very much best RC
