this is why I dont do craft fairs Ive been worried to much competition and it sounds cut throat.
Ive heard from several crafty friends that they dont make what the table cost.
And Ive tried for months and months to do one theme I was doing all clothing hats scarfs etc,just in various themes and sizes and find its easier to research what people want and do customs orders then to create a bunch of stuff no one wants. Be sure to ask for some money in advance on Craigslist or facebook, use paypal to do so thats how I do things.I found out the hard way people will order stuff and no show and then your again stuck with something no one wants.
I find in summer you have to change your inventory no one wants a winter hat in 99 degree days.
Even then in this business its hit and miss my sells are very much this way.
Also so many of people are selling copywrited items on etsy every time I go there my feed is packed with such items so im sure this is not a big issue and there not going shut one person down when there are thousands doing it ,I could link all day to people doing copywritted matterials such as disney pattrens dolls outfits etc . So im not sure how harsh these so called laws are. just the other day I saw a lady who sells crochet Bell dolls and other princess disney dolls and shes sold 200 of them acording to etsy.
So im not sure why people keep saying you cant sell it when everyone does .
I would just label it in a way they cant really get you ive heard if you lable it a certin way such as if your making hello kitty dolls call it white cat with bow , making a disney princess such as bell name it bell doll. Bell isnt a trademaerked name neither is white cat so when you lable it try to label it without anything that is trademarked in any way. I have seen this way used time and time again on facebook when people are selling items, I mean a cat with a bow isnt trademarked , so be creative in your labeling then you wont get in trouble.
just my experiences.
