Since having our daughter, I've taken up sewing. Making bibs, taggy cubes etc. I'm really enjoying it, however my daughter doesn't need all the bibs!. So I was thinking about maybe putting some on places like Etsy, Felt (could be an NZ only site) and Facebook. But I have no idea what to charge. There are similar styles to mine on FB that charge $15NZD (appr $12 USD) for their bibs - but only have one stitch - I overstitch the edges of mine cause I think it looks more professional. The pic is fabric for next lot of bibs on L and made bibs on R (dribble bibs). What would you pay?
Since you overstitch the edges of yours, this will likely make for return customers as well as those coming to you on recommendation of satisfied customers. So I would suggest a price that would entice first time buyers, say between 7-9 dollars a pop for these cute items.
Consider the material (fabric, thread, everything), and a decent price for your time. When you price your time, consider your sewing expertise as well, and remember that you will be spending additional time marketing, shipping, etc.
Make sure that you mention all the features in your marketing material so people know what the difference is between yours and the competition. Personally I wouldn't offer a discount to entice people to buy the first product, because it devalues the bibs. Offer something else, like a free gift with purchase (burping cloth?) for the first buyer.
