First of all: The five stranded double buns got massive. The five stranded braid has a way to flatten a bun a lot more than a normal three stranded braid, so these got big and flat. I like!
Second: The five stranded braid that was started as a three stranded braid and then added another two strands into for the next layer, worked perfectly fine as a bun base. It's not pretty when you can see the three-to-five transition, but as a base it worked perfectly.
Weird that the seven stranded braid from the other day got so messed up? Do the last two strands make that big a difference? Or is it because I'm not used to braiding seven and that messed it up?
