I love Moleskine journals. I recently bought several watercolour journals in the large size to tangle in.
One is for patterns, a sort of one stop shop for inspiration. It saves me flicking through multiple resources but is taking some time to complete as there are literally hundreds of tangles!
The other is for tangling in, and I bind them together with a bandolier I made to hold my tangle tools.
Yesterday I tangled one of the amazing Zendala® tiles and ran it through my Xyron with a laminate/permanent glue cartridge and stuck it to the front of my pattern book.
Today I Zentangled my daughter's initial on her first Moleskine.
