Thanks for your kind words!
Yes, I always BO buttombands 'in pattern'...otherwise the ribbing will be defeated.
I'm not home right now. But click my Ravelry notes link and read my notes. I give a boatload of tips.
With the bind-off-on-one-row/cast-back-on-next-row method of makind buttonholes...always use a pointy needle and work with very tips for the binding off...as close to the tips as possible...so that the stitches on each side of 'the bridge' don't become loosey-goosey. When working the next row...use the knitted cast-on method. Keep things as tight and tidy as possible. There are lots of buttonhole methods to chose from. A book that I've found to be invaluable is "Seven things that make or break a sweater". It's available on Amazon. It is G-R-E-A-T! Lots of finishing tips, too, in addition to buttonholes!
IMO, a bad buttonhole is like a pimple on Prom Queen's face!
