I have reached the end of the known universe with the beading on the Charlotte skirt. As there aren't any good pictures of the side or back of the dress, I am now going to have to make the rest of the pattern with educated guesswork, fairy dust, and caffeine.
Next goal is to finish the beading on the front of the skirt by the end of the week. Next week, the back of the skirt, then on to the bodice. I'm shooting to have the entire dress finished in about four weeks, so fingers crossed everything goes smoothly!
