I dropped the size down to about 11cm across and cut them from black card. There were lots of areas to back, so I stuck with plain cardstock as being easier to 'read' than lots of patterns.
I chose a rainbow of colours for both cards, going from purple in the middle to red/pink on the outside for Mandala 4, and then from red in the middle to purple on the edge for Mandala 8.
Both mandalas looked isolated/disconnected when I originally placed them on the white card-fronts, so I smooshed some ink onto the cards in pink/purple to match the colours on the outer edges of the cut-files.
Disclosure - I receive digital cut-files free of charge from Twilight Crafts as part of my DT role. All other supplies are my own.
