Don't know. So I'm going to brainstorm ideas at you to get me jump started.
1) Play. Get out beads, wire, rings, pretty rocks, and see what happens. Sometimes just staring at the sparklies gets me moving.
2) Go to the bead store. I usually see something I like and it gives me ideas. Except I have piles of stuff from past strokes of inspiration that isn't inspiring me anymore. *sigh*
3) Journal. If you're an artist who gets blocked sometimes, or you wish you were an artist, I highly recommend The Artist's Way by Julia Cameron. Or if you're not sure where you are in the stream of your life. It was/is a life-changing book for me. She recommends journaling every day as a way to clear the every day crap that's blocking your creative urges. I haven't been.
4) Sketch. This one's actually almost laughable because my drawing skills are almost nil (one of those things I comfort myself with believing I could be better if I'd spend time on it). Maybe that's not the way to go. Maybe I should paint with watercolors or even finger paints.
5) Walk alone, preferably in the woods. Nature speaks if you're quiet enough to listen.
6) Look at pretty pictures. I look at pictures of others' work that is similar to mine every day, and it often inspires me. But sometimes looking at amazing photography or paintings I like has the same effect, and it inspires me in a different way. Since I have a "Springtime in the Glen" theme to work with for Fantasy Artists of Etsy Exhibition, and Emerald Isle for Wire Artisans guild, I may peruse some knotwork and Celtic art.
7) Follow a tutorial. Whatever it is usually doesn't come out the same as the original in the instructions. I guess that qualifies as inspiration? Maybe I'll play with a new chainmaille weave.
What do you do when the muse goes south?
