The young ladies that designed the shirts are Ravenclaws at heart and, shall we say, dance to their own drummer (by themsleves, kinda flailing their arms. It's rather cute actually.)
I needed to make two bi color shirts from one black and one blue shirt, so one shirt had to be the mirror image of the other. K thought it was a rather Luna thing to do. I followed Jennifer's directions for the main shirt deconstruction and construction, but Logan's idea to remove the neck binding. After a bit of a struggle, I removed the entire neck binding from both shirts, and used a strip cut off the bottom of the black shirt to bind the neck edges (the shirts were a bit too long anyway.)
Since time was short, I chose to use a t-shirt transfer for the front patch, which turned out pretty well, and only took about 15 minutes. I followed Jennifer's advice and painted the lettering on the back. Two coats of white followed by two of silver sparkly. The final effect was really quite good.
Thanks again for the help. The girls loved the shirts and looked fabulous!
