This week my progress toward Level II of TKGA Master Knitter certification consisted of finishing the knitting of the right front and then blocking the back and both fronts of the vest.
Although I'm sure I'll have no problem doing the front bands and buttonholes, I'll be a good girl and halt the vest project for a bit while I dutifully do the buttonhole swatches that I haven't yet tackled. Several of the swatches in this level have to do with finding the best buttonhole for various situations.
I don't like overly large buttons on anything so I have always preferred the YO, K2tog buttonhole. I find it comes out a nice size no matter the thickness of your chosen yarn. However, as I'm finding out with each step of the program, you never know what you could do better until you give everything a fair try and do some experimenting. So experimenting with buttonhole options and doing the related swatches will be my self-inflicted assignment for the week.
