I did not use the 2x2 tiles (but I plan on doing those too) but I used a bigger rectangular one to use as a dry erase board. I used stazon and colored with fabrico markers. This was before I had every Sharpie know to man :lol: It can be propped up with a small picture easel or glue magnets on the back and put on the fridge. Use a velcro button and your dry erase pen is right there. I know you will get many more ideas on this great site, but thought I would put in my $$.
