I'm not sure whether you're talking about the fee to enter a quilt into the show, or a fee for a visitor to come look at the quilts. Both could be called entrance fees.
One of my guilds, the smaller one, had a quilt show in October 2011. We charged visitors $4 (an increase of $1 over our 2009 charge). We only had a few vendors, but we had close to 200 quilts, including those for sale, and we offered several classes/speakers each day, included in the entrance fee. We raised our price because other guilds in the area were in the $5 and over range. We never have charged for anyone to hang a quilt in our show, because we want to encourage community involvement. We don't usually have judges. Putting on the show required a huge amount of work and expense, and there was no guaranty that we would make a profit. The show is the guild's main way of making money that is used for community education, comfort quilts, etc. Much of our profit was from the sale of small quilts that were donated, as well as raffled items that were also donated. I don't think we would have made any profit if we relied solely on the admission charge.
Around here I think $10 would be too high for a guild show.
