Suggested Crease Patterns for Newbies

[JYangQi00]

I'd like to know if there are any crease patterns that can serve as a challenge to someone new to folding crease patterns. Also, I'd like to know if there are any prerequisites before folding crease patterns such as knowing certain techniques. Thanks!
