I've learned a couple of new techniques lately, like Magic Loop and using two circulars instead of dpn's. Today I finally learned one I should have mastered two decades ago - mattress stitching seams together. Wh00t!
It wasn't all that hard after all.
Now that I know how to do this right, I'm debating re-seaming the four strips I already have put together on my afghan so the whole thing looks better.
