My sister loves needlepoint, knitting, etc., and she recently decided to focus her crafts on all things Asian. I told her that there may be some uses in the tea community (even if it's just as art on the wall). I told her I would reach out to fellow tea-chatters to find out: a) what can she create that can be 'used' in the tea ceremony (or associated with tea storage, displays, etc.), and b) what pictures would be useful for her to use as references for her own creations (i.e., tea ware such as yixings or kyusus, cha wan, etc.).
Any other thoughts you have that may help her?
She's not a sales person at all, and is only doing this for passion so she's not the type to join Etsy and similar sites. Instead she will sell her art locally, but I also have 'personal interest' in this as I can get her to make me something cool for my upcoming birthday

To get an idea of what she has created so far, you can check out her site:
