Tear the book pages into pieces and use the gel medium to completely cover the index cards, make sure you overlap the pages. Once dry trim the overhang with scissors.
Choose 3 or 4 Gelatos in nice bright colours and cover the page by scribbling small boxes to cover the entire page - see picture below. you can use other patterns for different effects. No need to be neat! Be careful not to smudge the colour as you are working.
For this effect we do not want to blend or smudge the colours but we do need to "seal" the Gelatos so we can continue to work on the postcard and keep the colour effect as is. Use the gel medium and a spatula or paintbrush to swipe a layer over the entire card and allow to dry before continuing with the next step.
The next step is to stamp with your choice of background stamps and black archival ink randomly over the postcard background. Also use the stamp pad to edge the entire postcard to give a finished look.
Alternatively stamp the Dragonfly and Memories wording on white cardstock and use the water spritzer and ink sprays to "colour" the image with a thin layer of ink (a quick way to colour an image). Fussy cut the Dragonfly and tear out the "Memories" wording.
Layer the muslin, cotton and arrange the stamps on the postcard. Adhere everything to the card.
