Great as a visual for my clients.
Format: Spiral-bound
I highly recommend this chart. In my practice as a therapist I often go over boundaries with my clients and this is a good guide and visual for my clients rather than using the computer or sheets of paper. Clients have reported that it’s really helped them to understand more in our sessions about boundaries good quality and it’s erasable with the right markers.

Family Drama!
Format: Spiral-bound
This authors whole series is worth looking into. I did buy a few and passed them onto my sister’s family hoping it will bring them more together. I have heard back from one of them that they are working together on the flip chart. I have learned that there can be one person in the family that is the peace-maker:)
