Joe. I used to use an elastic strap under my legs for holding the dulcimer down, but it felt weird. It looked even weirder the one time I stood up and forgot I was "strapped". The dulcimer fell down my legs and crashed to the floor (sounds like a banjo joke). What I use now is a sheet of that weird rubbery material (the "sticky non-stic" stuff) under the instrument. Works fine.
