I submitted my first submission to a fairly well-known knitting magazine recently. I don't expect to be accepted, but it definitely marks a high point in my career. :) I feel like a real designer now!
Right now I am working on the testing of the revision for my Strawberry Patch Handwarmers. I felt soooo bad when I found the mistakes, and I almost felt like I had failed as a designer. But everybody makes mistakes, and I feel a lot better than I did at first. :) Besides, I took the opportunity to add some new sizes! So I can't wait to get that finished, but I am having a little bit of trouble finding testers. :(
