Doesn't it look so easy. Create a pattern, make it a PDF and sell it. Well let me tell you, the process is very very lengthy. First I come up with a unique design. I test it myself by using the item and having friends use it. I get feedback from them. The next step is how popular will this pattern be. I rely on my online community to get feedback in this area. Between my ETSY http://www.aggieray.etsy.com/ shop and my FLICKR www.flickr.com/photos/aggieray and FACEBOOK postings what kind of feedback are you getting on this new creation. I usually get questions on FLICKR where did you get this pattern? Are you selling it? and when will it be available?
The next step is to make the item, take a picture of every step of the process and decribe what you are doing and how to do it in simple terms. This takes me about 2 months to make sure I have a perfect pattern from creating the actual pattern, making the pattern pieces, testing the pattern and remaking it again to make sure the pattern pieces are acturate. The final step is to convert it to PDF format and making a good presentation page to get you interested in the pattern. It's a relief when they start selling and you get some positive feedback. I am working on my 5th pattern now.... it's going to be 3 patterns in one PDF. .... here is a sneek peak
