If necessity is the mother of invention, then sheer laziness must be the father! I have always found that my ingenuity is spurred on by work avoidance. This recent instance is one of my lazier better examples.
I just finished two Damson Shawlettes — one for a shop sample and one for the annual charity auction at my work.

My original Damson, plus the two new, unblocked ones
For some reason, I thought it made sense to block them at the same time. After all, I have two pieces of styrofoam for blocking and lots of pins. The first one went okay — putzy and boring, but okay. Then I started the second one. I had run out of steam and it wasn’t shaping up very well. I thought of just setting it aside for another day, but it was wet and I wanted it to be done.
Then the ‘lazy lightbulb’
went on!! The Damsons were made of the same type of yarn, same number of repeats, same size. Would it work to just double them up and put the second Damson over the first and use the pins as pegs? It worked like a charm and took a tenth of the time:

Here you can see the two stacked up:

Here are the Damson Twins after blocking:

As you can see, I used the open mesh modification for my Double Damsons, which I prefer. I love this pattern and LOVE the mesh version. I stopped a few rows early because of fear that I would run out of yarn, but I do think I could have gone the distance — I have a fair amount of yarn left over. Ravelry Project Page.
So, this was a great and successful blocking solution 🙂 with very little application in other situations 🙁 .
PS: Rox mentioned a couple of possible applications: You could block sleeves this way, couldn’t you? And maybe the back and front of a sweater, too?
I always use blocking wires instead of pins to block sleeves and sweater pieces, but this might help those of you who use pins. It will take longer to dry, but it might be worth it (?).
