I got an adjustable possum board from Jim VanderWoude at Evart. It fits all my dulcimers. I added rubber tubing to the posts and some additional felt in a couple spots to make sure the dulcimers don't get scratched. Very well made and thought out. It folds up too, for storage/travel.
Hi, how do they feel on your lap? Pro and cons? Jim lives close to me so would be convenient to buy from
Oh my, I just saw your question....sorry.
His possum boards are comfy on the lap. He also puts strap pins on it. The only thing is that the dulcimer sits a bit higher on your lap, but you can get used to that.
