Your first creation of crusader era clothing. The first few steps are aimed at the NEW reenactor or novice.

Step 1. Take a cotton sheet and fold it over and then again into a quarter. Make sure everything is even.

Step 2. Place a large t-shirt (or other shirt) over the sheet as shown, it will cover half the sheet and you might want to cut your cloth a few inches larger as you may want to wear a undertunic or mundane clothing under it. Use a pensil or chalk or other washable marker to mark your cut pattern.

Step 3. Make sure everything is even and carefully cut out your tunic. Again leave some room for it to be hemmed or to give extra room. Make sure your head can fit through the head hole.

Step 4. Unfold and sew up your new tunic!

This pattern can also be modified by length to make robes and is unisex in general. Trim can be added as can the cloth used. Old wool blankets can make very sturdy winter wear and look very period as well.
