Recycled Textiles Blanket

As you may know, I'm a sucker for making scrappy blankets.  My first scrap blankets started out as a mish-mash of crazy colors, usually not matching or complementary in nature.  I must say, some of them were pretty crazy looking!  Since then, I've designed a few patterns that can combine all these colors and make it look awesome!  
This spring I started designing a new blanket using all recycled yarn from either frogged projects or recycled yarn companies.  I am designing the blanket in panels, and sewing a recycled silk sari fabric to the back!  I'm also working on a cool icord join to attach the panels together.  I haven't really seen it before, I wonder if other knitters have tried it.  
It's been really fun taking apart old projects that I never really used.  Sweaters that just weren't flattering on me, scarves that never got worn, and others.  I like being able to give this yarn a new life in a project I know will be used.
I'm working on putting together either a tutorial of the icord seam and/or writing up the entire blanket pattern for my Ravelry shop.  I'm not even half done with the blanket, so it will be quite awhile before the pattern is complete.  I'll be sure to post more progress photos along the way!

Now I'm curious.. what are your favorite ways to reuse or recycle yarn?  Comment below!
