For example, for my Autumn series of which you see examples on this site, it started out with the death of my grandma (Mom's mom) who died just shy of her 98th birthday in September. September is an Autumn month where you can see changes of colors in the leaves and trees, a shift in the air, a feeling of ending and new beginnings both at the same time.
Going through her art supplies, I found a box labeled "oils" - I almost never paint in oils because it's much easier using Acrylics and she almost always used either oils or watercolors. I took it because I figured at some point, I would use them. When I got home and opened them a year later, I discovered that they were a line of beautiful acrylic colors - all Autumn colors - and I decided to use only those hues that I found in the box in a series dedicated to the memory of grandma - Charlotte Swanson Cleeland. It was like she had left me a secret gift after she died. After all, I get my talent from her - it seems fitting that she should continue to inspire me.
My first painting in the series, "Autumn Dance," took me a couple of months to finish as I did it in stages. I would put it away, look at it, see what I envisioned, worked on it, put it away, etc. Process. Like what we do every day. We are in the process of becoming more ourselves. Like most things, inspiration is a process and a journey - sometimes long, sometimes spontaneous but hopefully, exciting.
