Wool Stitching

My larger wool squares with wool pennies are coming on nicely, only a handful left to go before I have enough for a blanket. But, as much as I've been enjoying the hand sewing, I have been getting just slightly bored of nothing but blanket stitch. And Maria has been a little poorly the last few days (happily much better today), so I've had quite a bit of time cuddled up with her on the sofa, or playing a quiet game with her, and able to do some hand sewing at the same time. So, I decided to get some new wool squares and pennies on the go to let me mix up the stitching a little.

These ones are pretty small, 2 inches square(ish!). 

And I'm just doing whatever I fancy with the stitching. 

Don't worry, I'm not crazy enough to be planning on using these in any blanket sized project. I'm thinking they'll become a scarf, much more realistic! 

But even so, I think I might only be about a fifth of the way through with what I have here, so still a way to go.

I've got another, very slightly, lighter shade of grey wool that I had thought I might throw in the
mix for the squares, and possibly a greyish, herringbone pattern and maybe a dusky purple too. But now I have these all together, I'm not so sure I should vary the background tone. Any helpful thoughts?

Sally.
