London-born, Sydney-based artist Claire Cassidy, AKA Studio Flos, has earned a loyal following on both Instagram and TikTok with her playful paper-cut art, paintings, digital and 3D work. 

“Most of my artwork is teeny tiny and one of my goals this year is to work on a bigger scale, so it was super-fun to create these large painted paper vases,” she says. “I was inspired by the size of the Born A2 Recycled Kraft Folios and loved how they were a blank canvas for different colours and patterns.

This cool craft idea for adults also makes a cute homemade gift for loved ones, so gather your DIY crafts supplies and get creating.

Step 1

Cut the short edges off both ends of the Born A2 Recycled Kraft Folio, and fold it inside out, so that the inside is facing out.

Step 3

Once it’s dry, use paint pens to embellish the paint with abstract patterns and detail. Sketch out a large vase shape on the unpainted side of the folio. Cut out the shape through both sides of the cardboard. You should now have two identical vase shapes.

Step 4

Use an offcut of the folio and cut it to a 4cm wide rectangle, then draw a line, widthways, 1cm from the edge. Use this as a guide to mark where the holes will go around the edges of your vase. You won’t need marks on the top or bottom. Once you’re done, punch holes at each mark.
