I finally did it! I made a matching pair of mittens and both are the same size!
I have attempted to make mittens a few times now and with perseverance I finally got two mittens that I am happy with.
I used this basic beginners Lion Brand pattern, but instead of using worsted weight yarn which I was suppose to use, my daughter really wanted this yarn but it was a light weight. I doubled up the yarn and it worked out great, the mittens are cozy and warm.
