Sarah Bamford Seidelmann has published her seventh book, and this one is all about boundaries.

“We all want them, but I think they’re tough,” she said. “I sort of intensely studied them for 100 days in a row and shared what I was learning, what I was practicing, with my community on Facebook and Instagram.”

She got so many messages that it was clear other people related to the struggle. The 100-day project gave birth to “Boundaries Make Love Possible,” a workbook.

“I was diagnosed with ADHD when I was in my 40s, and I know that learning about hard things, I wanted to make it playful, fun, colorful,” she said. “Something that you could do bite-sized bits. You could do a page a week, you could do a page a day, you could take it on a weekend with you and get into it.”

Bamford Seidelmann’s artwork is also the subject of a short documentary, “Follow Your Feel Good.”

People can track her work on Facebook and Instagram.
