I'm building some cabinets out of 3/4" plywood, and I'd like to use 2x2" (nominal) stock as furniture squares. These squares will be on the interior only; it's not visually necessary for the interior wood to match the wood of the piece.
I'm planning on using a setup like this, except I'll be using 18 gauge brads instead.
Checking at my local lumberyard, it looks like this 2x2" stock is very pricey.
Would it be acceptable to use pine or poplar from Home Depot for these squares instead? The prices look much more tolerable.
Anything else I should consider?
