I've never had much of a yarn stash and have considered myself a "pattern stasher". I have printed and alphabetized patterns in assorted notebooks setting on my book shelves. I have a file drawer stuffed with patterns divided into knit and crochet, then subdivided into types of projects which are then alphabetized. Of course, there are my patterns neatly saved on Ravelry, whimsically separated into "Queue" and "Favorites" and in the pattern library. No rhyme or reason for me with my Ravelry assortment. Just click and save. I have personal pattern libraries at Lion Brand, Red Heart, and Patons web sites.
I have patterns saved to my hard drive, discs, flash drives, and on our netbook. That pretty much covers it, I think.
Now I have taken the next, crazy step. Instead of merely saving patterns, I am saving, printing, and starting to make the beguiling patterns, thus stacking up the WIPs. I am powerless to resist.
This is the latest WIP that's making me happy, "Country Fresh Blanket" with yarn I have on hand. The free download for this throw is at http://www.yarnspirations.com/pattern/crochet/country-fresh-blanket My colors are tan, burgundy, moss green, black, and oatmeal. It is now in rotation with my Christmas crochet and whatever else I'm inclined to do.
Are you a pattern stasher too?
