Re: Sewing Machine: Long Arm worth the extra $?
You also want to have a good heavy weighted wheel for hand work through thick fabric also. On our Sailrite LZ-1 sometimes using the heavy wheel to do the first pass was easier and broke less needles on some materials like strataglass for dodgers etc.
My wife has made dodgers, biminis, cover for the dinghy in the davits, web straps for thethers. and has just redid the 26 cushions in our boat.
We also take the sails home every winter and examine and do the minor repairs on our sails such as broken threads, webbing in the clue and headboard areas. The walking foot is a necessity.
If I was to actually make a sail the long arm would be a necessity as well as a good sewing table and catch table.
