Pre-wash the dress to remove sizing. Dry without a dryer sheet or fabric softener.
Fold your dress according to the tie dye pattern you desire. For the effect I got, I folded the dress like an accordion, then twisted it and secured a rubber band every 1-2 inches.
2. According to your tie-dye directions, apply the tie-dye to the dress. The tie-dye I used was one step, so you just add water and squirt on the fabric.
Wrap the dress in plastic wrap and let set for 6 - 8 hours (or according to your tie dye directions).
Remove rubber bands and wash according to your tie dye kit directions. For me this was just tossing the dress into a hot washer separately. Let dry.
Once the dress completely dry, attach the pom poms to the neckline with fabric glue or a sewing machine. Trim to finish.
