I would check the copyright disclaimers on the patterns of things you've made. Sometimes the pattern writers allow you to sell things you've made from these patterns, sometimes not. It could mean a legal infringement issue. If the patterns are yours, there's no problem. I think you would be better off selling your own patterns. There's nothing to ship and you could email them in .pdf format. There are many free programs online that will allow you to convert patterns to .pdf.
Welsh corgis are cool.
