and one of them is this gorgeous elaborate little metal frame -- and it has all these fun cutouts.. At first I was a bit intimidated but after giving it a go I now have some super easy tips to share with you!!
Start by mixing your equal parts A and B (yellow and white) of the molding putty. (I have actually found that it doesn't take very many extra seconds to measure out my putty in measuring spoons.. less wasted if my mixture seems to be off!!)
Flatten slightly (for my piece.. you may not need to do this!) and insert frame. Keep your fingers out of the way of your cutouts.. only go as far as you're comfortable... you don't want to ruin your mold.
