I was doing the same thing - selling them through LQSs. My one instructor said she stopped marketing her patterns because it wasn't worth the time and money she invested to produce. I haven't done much with my patterns lately but when I'm ready to do so, I'll probably sell them on etsy and set them up as .pdf files so they'll be easy to download and print from the customer's computer. Saves a lot on overhead.
Just a thought. Good Luck on your success.
