I do organize a craft show every December for our church group - it has grown from 8 vendors to over 30 in about four years.
Renting suitable space for finishing a project and/or photographing a project is an excellent idea. We don't all have space for larger projects. Also, lots of places do basic sewing/quilting lessons already but very few places do follow on lessons for intermediate and advanced skills. Another idea is an online sewalong for those of us who cannot get out and about to places. I've had tremendous fun taking part in knitalongs and crochetalongs in the last year. Most have been blogger led with a dedicated fb group so that people can help each other out and view wips and finished projects. I'd sign up to a sewalong in an instant, even if it was a simple patched potholder. I love seeing how others have interpreted the same idea, it's so inspiring.
I missed commenting on your last post. I look forward to reading all my favorite blogs. Usually in the morning with coffee. I would really miss it if it was not available. I don,t do Facebook or instagram. etc. Yours is one of my favorites. I don't blog myself, but I understand when those that do take a break now and then and I am happy when they return. Thanks.
Renting space to try or a long arm machine is off in the future. I'm still learning to while on my home machine!
