Here are my thoughts. First, I don't crochet, but it seems your prices are in line with what I've seen similar items go for.
Second, I looked at your sales, and you have sold 46 items this year! that is not too shabby! What prices were those items sold at? what is it that made you think you needed to raise your prices?
Don't underestimate the price of your time, materials, etc., and be sure you are getting enough for your efforts. Even on etsy, I think once for the materials, once for the work and once for your profit- so at least three times what the materials are costing you.
Third, have people told you that they are overpriced? have your vies or sales gone down since you raised prices? look at your stats, as you were raising prices and see what is happening.
I hope a fresh pair of eyes helps you!
Blessings!
