Here is how the tapestry looked right off the loom. You can see in the upper left corner where it starts to go in, and that's where I introduced the ribbon (also on the right side). I'm always experimenting with new fibers, especially synthetics, as they can add a lot of interest. But that added interest can come at a cost!
The next step is to pin the tapestry so that the selvedges are even – which means allowing for that shrinkage, by pinning the edges closest to the narrowest width:
The next step is the actual blocking. I use a wet cloth, and put the iron on the hottest setting. In the places where I have to allow for the most shrinkage, I hold the iron in place for a few minutes:
After blocking, it's looking like this:
As it dries, hopefully some of the lumpier uneven areas will shrink a bit. Stay tuned!
