What is the name of the spray that we buy to stiffen the bows? Also are the knitting needles a certain size? Would it be easier for us as pet owners (rather than showing) to get the bows on and off if we put them on a barette rather than bands? If so, what type of barette would you recommend? Thank you ever so much for the instructions. Looks like you stayed up until the wee hours to do that for us.
