I started off with four matching napkins. ^
And sewed 3 together.
Cut a neckhole in the fourth.
Gathered the first three and sewed them to the two sides of the fourth.
Added this just-right button to the back middle hem.
Not to my surprise, the shirt is really airy and poofy (so nice and cool, but also not /super/ flattering) but I really like it. :D It also reminds me mostly of a dress a 5 year old would have. But... I don't care. :)
