Cotton yarn or cotton crochet thread works best since the material absorbs the paste well. The size of the yarn or thread really depends on your preference. If this is your first time to try, we suggest size 3 for crochet threads and medium weight (size 4) for yarns. Choose white or beige if you wish to paint your ornament.
Synthetic yarns such as acrylic do not absorb the paste quite as well. A stronger paste is needed for this type of yarn, otherwise, the resulting ornament will be too soft to retain its shape.
Start wrapping the yarn tightly round and round the balloon. This step is probably the most challenging since the string tends to slip around the balloon's curved surface. Some suggest doing several vertical loops, then shift to horizontal loops, before making crisscrossing ones. We went with random directions and it still worked.
You don't need to cut the yarn, just go on wrapping until you're happy with how your ornament looks. If you find it easier to work with shorter lengths, cut yarn into several pieces, around 24 to 36 inches long.
Wrap the balloon with as much yarn as you like for a more covered or solid look or use less yarn for an ornament with wider gaps.
The idea is to soak the yarn with paste. You can do this by dunking or rolling the yarn-wrapped balloon in a container filled with paste. Gently squeeze the balloon to remove excess paste.
A less messy option is to use a sponge brush or an old kitchen sponge (cut in half or quarters). Dip the sponge in paste then dab onto the yarn. Press on the yarn for several seconds to let the paste soak in. Continue dipping and dabbing until all the yarn is soaked in paste.
Use a pin or any sharp object to pop the balloon.
In case your yarn ornament collapses, remove the bits of balloon. Insert a new balloon and inflate it while inside the ornament. This should restore the ornament to its original shape, though it will probably not be as firm as intended.
You'll have some flakes around the gaps of your ornament if you used white glue paste. There'll be even more flakes from the white glue and cornstarch paste that are thicker and slightly opaque. Since the ornaments are going to be painted anyway, you can just remove the larger flakes. You can click the photo for a closer look. I used the white glue and cornstarch paste for both ornaments.
