I love my M3 kits!! I use them for AJ but I also use them for regular pages. I treat them as I would any other kit. So depending on your mood, you can get messy or not. Most of the M3 kits have solid colored but textured paper included so you can keep it clean and simple. And do look at some of the older kits too. My favorite is from October 2016.
Hi Jennifer I have never really done art journalling before either, and was a little bit scared off having a go. Especially when looking at some of the amazing pages in the gallery. But having not scrapped for many years I have started back up, and I am beginning with giving art journalling a go . I just go with what feels right on the page, sometimes I add journalling and sometimes I don't. I have just subscribed to the Mixed Media Monthly Kit to use each month.
Here's what I did with the M3 for June 2017 - Difference/Grace/Acceptance with a few added bits for this months journaling challenge
