Whether it is a child, teenager or adult, you can make a terry-cloth towel robe for them, sized to fit, in the colours and patterns of their choice. All it takes is two bath towels, a little bit of sewing and the person to try it on. This is such an easy project that even if you have never sewn before, or you want to teach someone to sew, including children, this is a perfect project. The flexibility in size, length and pattern is a great stimulus for anyone to give it a try.
Identify which will be the outside and inside of the towels. Mark 6 inches in from the two corners along one of the narrow sides of one towel. Do the same for the second towel. These will be the shoulder seams. Lay the towels on a work space with both outsides facing up.
Place the two marked ends so they are just touching and pin them together with safety pins from the corners to the marks. This will be the opening for the head; check to see if the opening is large enough by slipping it over the head of the person it is being made for. Adjust the opening as needed.
Sew the two towels together to make the shoulders, using zigzag stitches so you have flat seams. Add strength to the ends of the seams at the neck opening by reversing the stitches for 1/2 inch and then going forward again to the mark.
Mark and pin the sides of the towels together about 16 inches down from the shoulder seams. Put the robe on the person and check that the arm openings are the right size for easy access and removal. Adjust as needed.
Mark and pin where the person's knees are. Sew between the arm openings and the knee pins using the zigzag stitch for flat seams the same way you did in Step 3, and reinforce both ends.
Check the overall length and hem it if needed.
Choose towel sizes appropriate to the size of the person. For a decorative touch to the seams, use contrasting instead of matching thread.
