What about hand-piecing a tumbler quilt made of charm squares?
There was just a post here on how to cut them without a template, very simple, and charm squares are very portable. (and fun to buy). I like the trapper keeper idea for holding everything. You could fit a mini cutting board in it with a small rotary cutter. 6 inch ruler would work for this pattern.

I used to hand piece at board meetings. It is very relaxing.
