Hey all, so I booked a table at a local convention next month. It'll be my first table and will be the one that decides whether I make this a regular thing or not. I had some questions for those who have done this before and those who frequent conventions in general. What is a good price in your opinion for prints and small take-aways? I plan on having 11x17 prints and probably some small buttons and stickers. I'm not well known among art sites and I'm still really novice in terms of art overall, so I'm not going to assume lots of people will buy my stuff so I don't want to over price anything, but I also don't want to under price and cut myself short.
Things like these are what's going to be available:

and stickers and buttons will probably be sold in small packs with 5 of each in every pack.
Also, keep in mind I have a large format printer and a button machine so I can print and make all this stuff myself without having to worry about print shops or anything.
Opinions????
