I finished the hat I showed you last week. The idea was that I would like to have a hat that I could wear even if I'm wearing my hair in a low bun. Therefore, I knit the bottom part of the hat in flat, so there is a gap in the back where my hair can go through. But I'll show you that in more detail later. Anyway, I wanted to close the gap with buttons and crocheted loops, but I couldn't find buttons to match my knit work. So I decided to make my own in the same color as the hat itself. It took me about an hour to find a good way on how to make button covers from yarn, and crocheting small circles to fit around the button worked best. I'm very pleased with the end result, and I will certainly use this technique again.
Sorry about the enormous text on the pictures, I have a new app on my tablet to edit my photos, but I'm still figuring it out :P.
