Craft Shows

So i have tried to do two craft shows, with no success!! i need some help! I did one show that was advertising as expecting over 1000 people to come, i paid $25 for the table and gave a $15 donation item expecting a great day, i made one sale yup 1 ... all of $6. I brushed it off and had high hopes for my next sale, paid $10 fee for table, and $1 so all in all im out $54 trying to do craft shows :(

Practice set up in my messy spare room 

 Does anyone have some great tips?
