Homemade costumes can be the best quality while being the least expensive. Store-bought costumes can be low in quality and not fit your child as well as a homemade one. With the popularity of movies such as "Harry Potter" and "Lord of the Rings," many kids want to be wizards for Halloween. It's easy to make your own wizard's robe, and you can customise it to your child's liking.
Measure the person who will be wearing the wizard's robe from his shoulder to his ankle. For small children, a bit above the ankle, around mid-calf, is safer to avoid tripping. Ask the child to spread his arms to make a "T," and measure wrist to wrist for sleeve length.
Fold your fabric in half width-wise. Match up the edges and hold the fabric with the ride side folded to the inside.
Use chalk to draw the outline of the wizard's robe on the fabric, using the dimensions you took, adding 2 inches to the each sleeve and 2 inches to the bottom for hemming. Ensure the fold of the fabric sits at the top of the robe.
Use sharp scissors to cut out your robe, being careful not to cut the fold you made at the top of your robe.
Pin the fabric together from under the sleeve to the bottom and the sleeve edge.
Use your sewing machine to sew along sides and lower edges of the arms. Remember to leave the end of the sleeves and the bottom open. Allow 1/4 inch to make the seam.
Turn under the hem allowance of the neck edge, sleeves and bottom. Use an iron to press the hem in place.
Use your sewing machine to hem.
Cut through the middle front of your robe from top to bottom. Make sure you don't cut through both thicknesses of the fabric. Turn under your seam allowance for the right and left middle pieces. Iron them in place and hem.
Hold the middle of your robe closed using Velcro or snaps, which you can find in any craft or hobby store.
