There is a trick to making pretty increases that I had forgotten. When you increase, to avoid having big, gaping holes where you did your increases, you have to knit through the back of the loop, to twist the hole closed. You don't see holes in my ugly mitten because I went in and darned them closed. But it still looks lumpy and ugly.
I knit these with double strands of yarn. One yellow and one cream-colored. The pattern of which color shows is completely random. I did the thumbs a different color under Vigo's design guidance. You might also notice that one of the mittens has a longer cuff than the others. That's because I was daydreaming.
To make these mittens, I used the recipe from Knitty. I love their basic recipes.
