Your very best bet with pricing is to look at the competition. Check out what other handmade things of similar style go for, then check out the closest thing in mass market. Make sure to check with the handmade stuff if they are actually selling things at those prices, or if their prices are just what they think.
For me, one of the things I sell for $5 - I think it's worth closer to $7, but the market is $5, so I do $5 (some sell for even cheaper here!). Another thing I sell seems reasonable at about $15, but the market is $20+, so if I drop it too low, I will bottom out the market, lose money for myself, and there will some people who don't buy from me because they think my product is under-priced and therefore inferior.
Love your items by the way!
