Blocks that should but don't match

Yesterday I wrote about how sometimes despite following a pattern for blocks that should be the same size, you'll end up with two differently sized/shaped blocks. I showed you Pink Stripes & Half&Half yesterday. Today, I give you my currently most extreme example:






BandOfBobbles & Half&Half could NOT be joined together or placed in the same blanket in their current form. They are supposed to be able to. I would have to rework one or both of them: by either working Half&Half in a size hook down, or increase BandofBobbles hook by a size or two. I might actually rework BandofBobbles, since I enjoyed it but wasn't satisfied with the end result, and see what increasing the hook size might do.
