Hi,

Together with my husband we had also built crawling track. At first it was for as a challenge because we have no flair for “do it yourself” things. But we did it!. We are from Poland and whole operation costs us approximately 30 USD. We bought all materials in DYI store. It was: plywood, naugahyde  glued with foam (is was prepared for door covering), upholstery glue, few screws. Plywood  was cut at our request at the DYI store. So we only had to nail particleboards up, glue door covering to the frame and woila. It wasn’t so difficult. Our two-weeks son has inaugurated our work of art wit a success
