Use your Cricut to cut the free Deathly Hallows free svg from the stencil vinyl. Use transfer tape to apply it to the canvas. If your stencil isn't adhering really well (don't want the liquid watercolor to seep under), use a heating tool (or blow dryer) to melt the adhesive a bit and then quickly press in place.
Use paintbrush to apply a thin layer of water over the exposed areas of canvas.
Fill the refillable watercolor brush with water and dip into the first watercolor. Gently apply pressure to the brush to apply color to the canvas. You may want to practice a bit on a spare canvas or paper until you get a feel for the brush. Continue applying colors until all the lines are filled.
If you end up with large pools of watercolor (which totally happened to me!), take a piece of paper towel and soak up some of the excess. Just make sure not to sweep the paper across your canvas or all the colors will mix. Allow this first layer of watercolor to dry completely before moving on to the next step.
With the base layer of color down, now you can add additional splats of color to the Harry Potter Watercolor Art. Allow this second layer of watercolor to dry completely.
With the paint dry, you can now remove the stencil vinyl!
Optional: I really like the look of adding a few additional watercolor spots outside of the lines but it's totally optional!
