One of the best workshops I have ever been apart of is this workshop when I was teaching boys to sew. Some of the top tailors today are men, and sewing teaches skills that all boys need to know. What an amazing time they have working with all the great fabrics and sewing supplies.
Workshops for youths are a great way of introducing boys and girls to sewing. In each workshop, the participatence will create a custom project. Birthday parties, youth groups, girl scouts, boy scouts, etc are great groups for this kind of workshop.
