It depends on the craft show. Higher end shows and established shows draw more people so $50 does not seem too high. Check to see how many vendors are coming and where they are from. Good shows will draw vendors from out of the area. On the other hand, for smaller or more local shows $50 sound too high. If you have never done a show then do not get expectations too high. It can be very dissapointing to keep hearing how "cute " your stuff is but no one buys it. Also you can make only 1-2 of each item so you do not have too much invested in product. Label them last one and hope it it grabbed up. Go to the show to enjoy the experience and have fun!!!!!!!!!
