I used 8.5 X 11 cardstock. I bought dot stickers in the stationary section of our local dollar store, then laminated the cards. I didn't calculate the cost while buying them, however from Frukc's estimate of 5500 dots needed, it would have paid around $15 or $16 for the dots - $1.00 per package & 364 dots per package. I also had the cost of cardstock & laminating ( you probably don't absolutely have to laminate, but I prefer it).

What is the size of dots?
I saw some in target but they were very few in $1 .
They were around 12 in $1 , thats why i said it could be costly.
Thanks
