Diamonds That Don’t Stay Attached
No matter how much precision you put into applying diamonds to your canvas, sometimes they are simply too stubborn to stay in in place. Finding one of them laying on the floor hours after you have completed the painting can be very annoying. It's important to realise it’s not always a sign that the glue you used didn’t work.
Solution - When you have completed a painting you should always leave it standing up. During this time if any of the gems misbehave and fall out of their spot, you can use a toothpick to press them back into their squares.
