I sew whatever I can fit between the presser foot. MOstly guitar straps, belts, pad folios and gps tracking collars for cattle
As has been said before, the 206 really isn't a holster machine. It doesn't have enough capacity or take big enough thread. However, you do what you got to do. When I make holsters, I sew the linings on, and when I sew the two halves together, I hand stitch that part.
Use to take me 4-6 hours to hand stitch a guitar strap or padfolio. Sewing machine takes less than 10 minutes. And my hands don't hurt afterwards. One of these days ill get a 441 clone for big stuff like nice double lined holsters and saddles.
