Rack Question

on the rack im building i was just wondering if the back piece should be solid or have holes in it for some circulation..just wondering.. buy the way im using belly heat..

I suggest making it solid. It will keep in the heat a lot easier. No need for the rear vents IMO.

when i made mine i drilled two holes in the back for all the chords to come out and it works good. it keeps the heat in and allows for ventilation

You may want holes to run your heating cords through and probs.
