Directions for alternate side looping/husking can be found in this recent quilled Valentine tutorial. You'll create loops of different sizes by hand, gluing each one at the heart base as you wrap the paper back and forth from side to side. (no need to use straight pins and a board - I find that method is too fiddly) Unlike the husked leaves as seen at the link, don't surround the loops as the final step. Instead, hold the base and curl each loop with the edge of a scissors blade.
I printed the interior message on a square of patterned paper and quilled a small motif for each rounded corner made up of two flag scrolls and a heart scroll.
To make a heart scroll: Fold a 3 inch strip in half. Roll one end to fold, allow coil to relax, and slip it off tool. Repeat with opposite end.
To make a flag scroll: Fold a 3 inch strip in half. With strip still folded, roll ends together toward fold.
I like the way the sheer ribbon with solid edges goes with the lines in the embossed card card blank by DCWV. I think this card style has been discontinued unfortunately, but I've seen them at Michaels in boxed sets.
Hearts can be used for more than just Valentine's Day cards - engagements, weddings, and new babies come to mind. And so I made this version with pale pink and silver-edged quilling paper and topped it off with a bit of angora yarn. Hmm, the heart looks more like a shamrock though.
