There is always something new to learn, a new tip, tool, way of doing something, and new uses for everyday items. What I know for sure is that I don't know everything, and life is too short to learn everything I want to learn or make everything I want to make.
Most of us have learned a lot by trial and error. By taking a class, we can avoid some of the frustration of trial and error mistakes, not to mention the expense of wasted supplies. There must still be practice of a new skill to get it right, but with a class, you have the knowledge to perfect that new skill and make it work for you. You may already know how to do something but taking a class in that same technique may be just what is needed to get new ideas flowing.
Many of us cannot attend classes in person. On-line classes are great, especially when you can interact with others taking the same class at the same time. The best part about purchasing on-line classes is that usually you can view them over and over again. And with today's technology, you can zoom super-close in to see a specific technique, something you could not do in person. And new tools-don't get me started. I can't tell you how many tools I have purchased after viewing and/or using them in a class and found how much easier it was to do certain tasks with them!
Taking classes gives me the push I need to finish old pieces and/or start new ones. After seeing the Limited Time Offer of "Scrap Casting Fabrication & Jewelry Design" with Kim St. Jean for FREE (I own this course) on wirejewelry, I pulled out all the pieces I cast in my garage this summer with scrap silver. Then I started playing with some unfinished components I made during the year but never got around to finishing. All I need to do now is to add chain. During Holiday sales, I stocked up on snap sets and CZ's and have had a blast. So, even thinking about a class I took gave me the push I needed to finish some pieces.
