How to Cut the Seams of an Old Shirt
Lay the shirt on a flat surface.
Unbutton any buttons and spread the shirt open, if applicable.
Cut off the collar or neckband. Discard a t-shirt collar and purchase a new one to make a t-shirt. For a button-down shirt collar, cut the upper part of the collar from the lower half of the collar.
Remove the sleeves by carefully cutting along the armhole seams. Cut open the seam in the lower edge of the sleeve, and cut off any cuffs.
Cut along the side seams in the shirt from bottom to top.
Cut apart the front and back of the shirt at the shoulder seams.
Cut open any darts or pleats in the front of the shirt.
Cut off any pockets on the front of the shirt. Ignore the hole in the front of the shirt when making the pattern.
How to Make the Shirt Pattern
Place the back of the shirt on a large piece of paper or piece of fabric.
Measure 5/8 inch from the edge of the old shirt to mark the cutting line for the new shirt back. Use a pencil to mark this distance on the paper, or use a pin to mark it on the fabric.
Repeat step 2 all the way around the shirt back, so that the pencil or pin markings for the new shirt piece are 5/8 inch larger than the old one all the way around.
Repeat steps 1 through 3 for the sleeves and cuffs, if any. For cuffs, you’ll need to cut two pieces of fabric for each cuff and sew them together.
Repeat steps 1 through 3 for the shirt fronts. For a button down shirt, also add 3 inches to the button areas, so that you can fold the fabric over to make placards for the buttons and button holes.
Repeat steps 1 through 3 for the upper and lower parts of the collar, if applicable. Remember that you’ll need to cut two pieces of fabric for each part of the collar and sew them together.
Repeat steps 1 through 3 for any pockets.
