I'd be doing the bleach part of this technique in my laundry room in old, old clothes. If there's a disaster that I could create, I'll probably do it! It's the same reason I don't have any drinks (alcoholic or not) anywhere near my crafting table. Are we getting close to a new morning coffee video (my time zone)?
When I saw you use the embossing powder it brought to mind a QUESTION. Is there a non shiney (matte finish) embossing powder out on the market? Tulips are really great. Not sure about bleach smell.
