I found Whitney after she left a comment about the Easter dresses (see previous post). She saw my tutorial on Threadbanger -- and so she made her own!
She's really good, so I thought I'd share her with you. One thing I especially liked was her use of sidewalk chalk as a marker. Now that's just plain genius.
One thing I would have done differently was use a measuring tape to mark the hem of the skirt on the paper. At the top left corner of the paper, anchor the tape at the finished length measurement with a thumbtack or tape. The other end of your tape, (the beginning) will have a little metal end with a hole in it. So just use a pen or marker stuck thru the hole and mark your paper as you move the tape from the top of the paper down, to draw an arc from the top to the side, forming a quarter circle.
