Barnbum!! don't put it on a shelf til you are bored!!! Get out there and write it up and promote it!!! do it!! do it!! do it!!!
I write up patterns all the time where I teach and make my own designs! When you do write it up find someone who will be a test quilter to make sure everything is explained right as they are making it. then get out there and promote it!!!! Approach your local quilt stores, the local guild, friends and family who sew!!
At the moment I am making a line of tote bags for the summer. So far I havent' spent a dime on advertising but its been all word of mouth. I have several orders now. Some of them sight unseen!!! I started a list several months ago on every possible way I could sell my designs with as little money as possible. Most of my list is FREE!!!!!!!!!!!
I'm alllllllll for people wanting to make money doing something they love!! I'm all for entrepreneurs!!! I love your design!!!!
Cheers
