Thrummin' Right Along

I decided to "thrum" a pair of mittens I'm making to ensure they are toasty warm. I'm using leftover yarn from her hoodie rather than picking a warmer yarn. I bought my first ever chunk of roving from Marr Haven http://www.marrhaven.com/rovngdy2.html

For some reason, the phrase "thrummin' right along" keeps playing through my head as I'm working on them ... to the tune of the Muppets' song "Moving Right Along", which makes this project all the more humorous. Oh yes, and I think the roving kinda has the texture of Miss Piggy's hair!

Here's what the project is looking like so far!
The makings for the inside:

The outside:

And the hairy, toasty warm inside!
