I love adapting the imagery I do in ACEO format to other sizes. This is the ultimate adaptation: a tattoo! How I do tattoo design is basically a client commissions the artwork, I do it on either paper or canvas and they get to keep the original piece plus authorization to use it as a tattoo.
Its always so touching to find the reasons behind a new tattoo. So many people use them to mark a milestone or a memory. Its even more touching to be included in the process.
