I recommend picking a small handful of characters you would like to do and go from there. Then we can narrow it down to something doable for you. Suwako and Hatate are two characters that haven't been done to the point of excess, but would still be easy to do. Both would require a bit of sewing, but I always think this is a good thing because (1) it's your own creation, (2) sewing isn't too tough to learn so long as you have a machine to work with and someone - anyone - on hand who has used one before and (3) sewing's a nice little hobby and not a bad skill to learn either.
Remember, there are a few of us around here who have done this stuff in spades, so don't be too afraid to start out.
This also reminds me that I should consider pestering someone else about starting.
