If this is something you expect to need for a while, you might check with the dealers about an industrial machine. I have an old industrial machine that I bought from my son when he got married and needed $$, he bought it to use making car upholstery and it was owned by a man that had used it for that originally. It's at least an early 50's model, works super, uses same needles as my long arm, will zip though 4 layers of heavy duty denim, handles leather, upholstery fabric and about anything I put under the presser foot. No fancy stitches--just straight with a reverse. It's very heavy and I don't use it for much other than heavy duty stuff--but it's great for any kind of bag.
