linoleum cutting supplies

[1967-colt45.livejournal.com]

sorry for the text only but i was just wondering if anyone of you knew a place online where i could purchase some linoleum blocks for block printing. i just acquired my mom's old block cutting supplies and i'm really excited because it's something i always wanted to try, i just dont know where to find the blocks. i'm guess you can't just buy the kind at the hardware store?
thanks for your help!
