Well it has been such a long time since I posted a tip here.
My newest suggestion for cosplayers looking for commissions is really know what you are looking for before approaching a commissioner.
I have come to a point in my commissions that I am selective to who I want to work with based on their intial emails to me.
I now have
http://www.pegasusmaiden.com/cosplay to help me sort out orders. The website is great for your to submit a form that tells me what you want and what you expect so I can give you a comfortable price.
When cosplayers approach me with 6 costumes asking for pricing it is overwhelming and also costly on my time to do the research. I understand that everyone does shopping, but it really helps when you can narrow it down to 2 instead of half a dozen.
Budgeting is very important. Do not commit to a commission that you think is above your budget because that makes it difficult for the commission to fulfill your order if you can not make the last payment. It ends up with two unhappy individuals.
Cosplay is a luxury and a hobby I advise that everyone to take care of their personal needs and housing needs first before they consider getting a commission. There is plenty of time for fun and leisure, but prioritize your basic needs first before you spend your money.
Overall have fun with cosplay you will enjoy it more when the commission you want is not a hole in your wallet.
