Have you heard about issuu? A great place to publish - or find - information of all types. I'm usually looking for quilt or craft patterns myself.
If you haven't found this website, you'll have to check it out.
Here's one of my embroidery designs that I've published there. The presentation looks so professional, doesn't it? Oh, and I like the pattern too! :)
I think it's a great place to publish free patterns so everyone can find them easily. You can also embed your patterns from issuu to Facebook or on your blog, like I'm doing right now.
Let me know what you've found on issuu or if you're using this website to publish your ideas.
