Don't worry about the guys being teased. You can pump them up so that they are so proud of their accomplishments that they will be excited to show their work. Then, before you know it, their guy friends will want them to do one for them. My son had an extra elective to take in his sr. year of high school so he took a home ec. class. Well -- he learned to service my sewing machine and he made an awesome set of vinyl covers for his guitar amps. Really impressed his friends! Have a great time with the boys.
