Vestments such as the chasuble are primarily used in the Catholic faith to honor the Holy Communion (also called the Eucharist), a tribute to the body and blood of Christ. The garment is perceived as one that has to be ornate in design, but, when making one yourself, starting out with simpler patterns is advised.
Select your pattern. Ensure that the fabric you use is made out of rayon and specifically designated for vestments.
Lay your fabric out on the cutting board. Fold the material according to the pattern's instructions with the pushpins set in place on the specified lines. The largest fold should be directly down the center of the garment.
Begin cutting along the lines of the pattern, ensuring that there is 1½ inches of space between the edges of the garment (including the neckline) and the pattern itself. This will give you enough room for the seam.
Unfold the fabric when you are done cutting the pattern and neck hole. Once this is done, the banding can be added. To determine where to place the banding, measure approximately 9 inches down from the neck hole. Mark your fabric at the 9-inch point with chalk to designate the banding placement. Make two other markings with your chalk starting from the center sides of the neck: One that is 9 inches from the left and one that is 9 inches from the right.
Place your banding on the chalk marks previously indicated. The v-line of the chasuble can be made by folding one piece of banding on top of the other, using the line of the design as your guide in terms of evenness. Determine the placement of the banding for the shoulder seams by folding the banding over itself, just as you did for the neckline. Once you have made these demarcations, sew it together.
