T-Tunic and Sash

I like to sew and make my own clothing. By far my favorite piece of clothing is the T-Tunic. Simple to make, original, and elegant. You can wear them to Ren. Fairs or just around down. Tunics are traditionally tied with a belt or a sash.
The first thing to take into account is the season in which you will be wearing tunic. Spring and summer tunics are the simplest to make, and that is what I will describe here.

Fabric
Fabric is an important thing to take into account. A tunic is essentially a long, open shirt, so your fabric needs to be something study, in case it catches. You need to buy enough to cover you. Two or three yards should be plenty, maybe even with enough left overs to make a matching sash.

Cutting
The brilliance of the T-tunic is that it can be made by a beginner, alone, without a pattern. Lay your fabric down on a clean bit of floor so that it only has two layers, and these layers are perfectly even. Lay down on it and adjust yourself so that the top edge of the fabric is just above your shoulders. Stretch out one of your arms. With some sewing pins, mark next to your shoulder, and then your elbow. Do the same on the other side.
Also mark on either side of your hips. There's no need to properly pin the fabric yet, just stick the pins in there, so you know where the places are. Get up again, and properly pin the two layers of you cloth together. You may have adjust one of them. Cut out the shape of a large T for your body and arms, just a few inches wider then your hip marks. leave at least 5 inches of witch in the sleeves.

Sewing
Hem the rough edges, and then cut and hem a hole for your head.
You can make it as ellaborate or as simple as you like!
