I realized recently how much money I've already spent on this challenge in materials, so I set myself a special challenge today: to see if I could make a book for literally pennies in materials.The lotería cards were cut from one big card from a set I bought in the open market while I was in Mexico. I think the whole set cost about $3, which means the part I used is worth about 15 cents. The pages are cut from brown painter's masking paper. It's t hin and slightly shiny on one side. I bought it at a paint store, in a roll 9" wide by 180' long for about $1.50 For the pages, I used about 15' off the roll, sot he paper cost me about 13 cents. The two feet or so of blue hemp cord was about 5 cents and the 6 beads were 1/2 cent each.
Total cost of this book in materials = 36 cents. So I guess I managed to meet that challenge.
