DO it!!! You'll never know how good you are until you try. Don't believe that rejections means you're NOT good, either! They can only say no! Then go back after you're accepted/rejected and see what's being shown there. It'll give you an idea of what to do or not do.....
I had a woman approach me years ago to put some of my paintings in their JURIED church craft show. I was so reluctant, but finally did it. ALL my paintings sold in the 1st hour. I know, because I was there an hour after opening!!!!! Sure gave me a boost!
Let us know what you do!
