What a find!

I found Jeff Mack Supply while looking for wood to make a bench for my front hall-way. I had decided on cherry and Jeff helped me choose the right size for what I needed. After I chose my wood he had it dressed while he helped me choose the right varnish and gave some tips on how to do everything the proper way. All in all a wonderful place. Thank you!

Really nice

I just started playing and and the plastic pegs were hard to get a grip on as many of us are arthritic but yours make it so easy to grasp and are pretty as well. Glad I found you.
