Sometimes (ok, a lot of times) i decide in advance that i don't want to try something new. Reasons - too much trouble, not necessary, takes too much time to learn.... etc. And, sometimes, after trying a new something, i find it was fun and/or i like it!
I've sewn since i was about 8 years old. I've enjoyed many aspects of sewing with a major emphasis on making quilts (started making quilts in 1976). I shunned the practice of machine embroidery until early spring of this year. Now, i am sad that i didn't try it sooner. It's SO MUCH FUN! I am lucky that someone persuaded me to take a class that i really didn't want to take. I still have so much to learn with regards to embroidery on the machine and creating/adjusting designs. But, now I can see value in working thru what is for me a large learning curve.
