Bathrobe patterns come in a variety of styles. Typical designs include set-in sleeves and a shirt collar, or raglan sleeves, which are sloped at the shoulders, and a "Peter Pan," or small rounded collar. A favourite among many for its comfort in wearing and simplicity in sewing is a raglan sleeve robe with a shawl collar, or a collar connected to the front robe facing that simply turns back along the back and neck of the robe. Attach the collar and facings when the robe is almost completed, with the back and front pieces connected at the shoulder, the sleeves attached and the side and underarm seams sewn.
Sew the centre seam of the collar by placing the two pieces right sides together and stitching a seam. Trim away any excess seam material down to one-half inch, and press it open.
Fit the collar to the back neck of the robe, right sides together. Stitch, then trim the seam. Clip the seam where it curves along the front and shoulders by making little straight clips with your scissors at right angles to the stitching. Do not clip the stitches. Clip the collar seam at each shoulder seam, then press the front seams open and the back seam up toward the collar.
Place the fusible interfacing pieces on the facings. The interfacing goes on the wrong side of the fabric with the fusible side down. Iron it on with an iron set on "cotton" or "high." This usually takes only a quick swipe with the iron.
Join the facings at the center back. This will create one long strip of fabric. Hem the outer edge of the facing by turning facing and interfacing under one-quarter inch; turn it again, and sew it in place.
Pin the facing to the robe, right sides together, matching the raw-facing edge to the front edges and collar of the robe, and matching the centre of the facing to the collar centre. Sew the facing to the robe, easing, or slightly adjusting, the material to fit as you sew. Trim the seam, and clip the curves.
Turn the facing to the inside, and press. Slip stitch by hand with a needle, and thread to hold the facing in place along the shoulders and back neck of the robe. Slip stitch by running the needle through the hem of the facing, then out, to just catch the seam fabric. Keep the stitches about one-quarter inch long.
For very heavy fabric, like terry cloth, you may want to use seam binding along the hemmed edge of the facing and collar, rather than folding it over.
