I would Love to see this done with plushies. Imagine having a pdf printout where an artist can put together a standard-sized bag or a box to fill with a plushie and trade to across websites like swap-bot or deviantart.
This movement of plushies and fanart is so incredible to me. It unites so many people across different age groups to share in the fun of sewing, drawing, sculpting, and animation, all while bringing out the inner child in someone.
Being able to interact one-on-one with the active artists of this movement by trading lovingly-made plushies, essentially soft and huggable art, could be so rewarding, don't you think? :)
