I usually use the 1" strap (which I prefer), but the 2" strap is also very nice. For some heavier, more-substantial dulcimers, this one might be better than the 1" strap. Either way, this is the only strap I ever use anymore.
I love my new dulcimer! The sound is excellent. I went with a shorter board, which helps a lot since I am short and have smaller hands. The whole instrument is lighter and easier to manage than what I had been playing. Also, Folkcraft has so many choices for resonance designs to personalize your instrument, and I love the brontosaurus engraved on mine. Have been playing it most every day for a few weeks now and am very happy with how it came out.
I find this strap to be very sturdy. I love the fact it breaks away in two spots. I am going to get a 1 1/2 in strap for my ukuleles with pickups that have large buttons that are difficult to get a strap on and off. This solves that problem.
Works wonderful and is adjustable and easy to switch between dulcimers. Have not tried on a one of my uke's yet.
I recomend these because they are comfortable and don't twist like other straps. They look sharp and they come in different colors. Give them a try.
