Are you paid what you're worth?

I was hanging around the Etsy forums the other day when I came across a thread about pricing your items to get paid what you and your items are worth. A fellow Etsian, Chris Parry, has a great blog post about this subject, even offering a spreadsheet to help us figure this whole thing out. After evaluating my goals and spending some time with the spreadsheet...I need to make some changes in my shop. Do you? Thanks Chris, for the helpful info!
