Hello! i myself do not have a tutorial made up but i can point you in the right direction of the tutorials i used as reference while making my wings! here is zippyc’s tutorial and dersedreamer’s tutorial :3 i used both as a reference throughout the entire process of making my wings and i do suggest that you take a look at both because they are both really helpful and are both really kawaii people in general (◡‿◡✿)
as for advice, i will say:
letter a) do not do not give yourself a deadline. take your time making your wings and make sure everything is right/the way you want it to be
letter b)make sure you’re working in an area where it is easy to clean up after yourself. i worked both in our living room and my sewing room and i know there are still remnants of feather clippings in between floorboards and under the sofa and behind the tv, etc… ((throw away the feather clippings as well, dont just, like, let them be free in the outside world lmao))
letter 3)make certain you have enough supplies and restock if you think you might be needing more before you actually run out. i /know/ i used a lot of hot glue working on this and every time we went back to jo-ann’s i was getting more hot glue sticks
and number d) have lots of reference pictures! make a specific folder on your computer for refs and progress and all stuff related! i have over 40 pictures of crows/crow wings/bird anatomy that i had out on my screen every time i worked in this thang.
… yup i think thats it! if you have any other questions about anything, feel free to message me! ill try to help the best i can! good luck with your cosplay :D <3
