Oh My! I'm having a heck of a time with clue #4. Clue #3 was challenging for me, yeah, I know it was just squares but UGH! I have ripped out clue #4 more times than I can count!! I keep confusing the A and B block, I'm so frustrated but WILL NOT QUIT, I need to get through this, I've spent so much time on it so far! I swear there are gremlins who keep switching my blocks around! UGH!!
