After bleach/developer has been applied to knots, and after the bleach/developer has been blow dried, and while you are letting the bleach/developer sit on the lace for 10-15 minutes or so, should the hairpiece be placed upside down so that the hair is against the table the hairpiece is placed on? This way the bleach/developer can work its way down the knot a little bit. Or should the hairpiece be placed right-side-up so that the lace side of the hairpiece is sitting on the table the hairpiece is placed on? Again, this is for when you are letting the bleach/developer sit on the lace to let it work itself into the knots.

Thanks for any suggestions.
