    Measure the Fabric

    You only need two measurements for this robe:

    1. Measure from your shoulder to your ankle. If you want the robe to be shorter than ankle-length, measure to your knees or calf.
    2. Measure from wrist to wrist to determine how long you want the sleeves of your robe. If you want the sleeves to overlap your hands, then add a few inches to the measurement.

    Cut a rectangle of the black fabric that is twice the length of your shoulder to ankle measurement. Now cut an identical rectangle from the red fabric.

    Fold the black fabric exactly in half. Make sure that all the sides are lined up.

    Trace Your Body

    how-to Gryffindor Robe
    For a baggy robe, trace farther from the body.

    Lie down with your shoulders at the top of the fabric and spread your arms out as shown. Spread your feet about a foot and a half apart.

    You'll need a buddy to trace the shape of the robe around your body.

    For a billowing robe, trace farther from the body. For a robe that has a closer fit, trace 5" or so away from the body.

    For the sleeves, start 8" from the top of the fabric for a close fit. Trace 14" or more for long, draping sleeves.

    Once you make your marks, go back and adjust your lines to make sure the measurements are even. If one sleeve is 18", make sure both sleeves are 18" and so on.

    Cut Out the Robe

    Cut through both layers of the black fabric, making sure that the bottom layer doesn't bunch or shift while you're cutting. Don't cut the top of the fabric where it is folded.

    Open up the black robe cut-out and lay it on top of the red fabric. For a lined robe, you will need to trace the cut-out robe on the red fabric to make a perfect match. Cut out the identical red robe.

    Stitch the Sides

    Sew the sides, then cut the opening in the front.

    Fold the black fabric so that it is inside-out.

    Use your sewing machine or hand sew a straight stitch along bottoms of the sleeves and the sides of the robe. Use about a 1/4" seam allowance. Zigzag stitch the raw edges to prevent them from fraying.

    Use your measuring tape to find the exact center of the robe and mark it. Cut all the way up through the front of the robe. Do not cut through both layers. Repeat this step with the red fabric.

    Press the Edges

    Iron the edges to make sewing much easier.

    This may seem like a trivial step, but it is going to save you time and hassle while you are sewing and makes the finished product look much better.

    Use your steam iron to press the raw edges of the cuffs, bottom hems, and front openings of the black and red robes. You will need to fold in about 1/2".

    Once your edges are ready, you can sew the lining to the outer robe.

    Insert the Lining

    Pin the red robe inside the black robe.

    Turn the red lining robe inside out.

    Insert the red robe into the black robe, making sure that the seams line up and that the sleeves are not twisted. Line up the pressed edges of the cuffs, bottom hem, and front opening. Pin in place.

    Once you have it in place, then you can top stitch the robes together.

    Stitch the lining in place.

    Now you will stitch right through the top of the black robe to secure the red lining in place. Stitch along the cuffs, then the front opening, and finally the bottom hem.

    If you pressed your edges, this step should be very easy to complete. Once your robe is put together, you can add a Gryffindor iron-on patch to the front, or even tack a few buttons on the front.
