This summer I went old school with a no layer card...just stamps and ink on a 110lb white card stock base. I created 24 cards in a good 8 hours, using only Hero Arts inks and Hero Arts Poly CLEAR stamps.
inks: charcoal (sentiment); the five inks (two greens and three reds) are all from a "my monthly HERO creativity in a box" kit from October 2015.
stamp sets: "Thanks a Bunch" and "Layering For You Flowers"
