they are my favorite thing to do! I love making people
I definitely would say that patience is a must. But I wouldn't say they are hard to do. Designing a new one can take some hours because I keep changing things. But once I have the measurments and techniques figured out, I can make them quicker, I'd say some smaller simpler ones I can do in 20min, but some will take me a lot longer, like the Mary Poppins takes me quite a bit longer for some reason. If I have many to make, I do them in stages and take breaks. Though I probably wouldn't need as many breaks if I didn't have kids and a dog running around interupting me all the time LOL!
