Theoretical answers.....
Smallest I've ever done is about 3 inches tall (it's my rubix cube), Largest I've made is 18 inches tall (it's Finn from Adventure Time).
I can bigger ones, but the pirce goes up the larger it is.
I started out designing and making my own creatures and characters, I still do, I've just been doing some anime/cartoon ones lately.
I can work from an avatar, as long as it isn't too crazy. The price goes up with the complexity.
The simplest plush I've done is... probably... my octopus (unfortunately I do not have a picture of it). The most complex I've done is... probably Finn, he took a lot of different colors and parts to make.
I am willing to make more complex ones, bring on the challenage!Small is about 3-8 inches tall 10-15$, Medium is 8-18 inches 15-25$. I've never made a "large" in my opinion.
In general yes you do ask a lot of questions, but they are all very
smart questions!
