Several months ago I dug up my old art bag from when I was a student at The Art Institute (Pittsburgh) just to discover someone has rummaged through it. Much of m y work was ruined plus my 'drawing board' and aluminum T-Square missing. Now members of my family just don't get that as far as I'm concerned, this is a 'Hair-on-Fire' catastrophe. My income is well below the poverty level -and- T-Squares & Drawing Boards are obscenely, ridiculously, unjustifiably expensive.
So...I went to Home Depot and bought a piece of plywood 24 X 24, duck-taped the borders and papered taped poster board on the front the same as I did while going to The Art Institute.
Arts & Craft Stores: $50.00 & up
but a 24 X 24 piece of plywood from Home Depot: $8.35
The T-Square was $9.00 at Michael's with a 50% off coupon.
Happy as-a-pig-in-shit: Priceless
