|Not sure most people are aware of the free sewing resources, projects, and advice offered through the extension service offices at many state university websites. These offices are part of the land grant college system in the US, and generally provide services to the community at large, not just students enrolled at the school. If you are interested in gardening, canning, food preparation, ....., you'll also find information on those subjects. they are too many extension offices to list individually, so search for "university extension service" and browse to your hearts content. Use "sewing" as a search term on the site to locate specific sewing articles.
here are a few examples:
I noticed that the Utah State extension service offered a one day sewing "camp" last year for kids (beginners and intermediates); wouldn't that be a great thing to send a pre-teen or teen to? North Carolina offers classes as well, and I am sure the others do also.
Did I mention free? The web content, at least, you should expect a small fee for classes... $10?
