If you are like me and get confused sometimes when adding your tiles and they show up in all the layers so you can't tell which layer is which...... here is a little tip that may help.
Copy and paste your cheat sheet as normal.
Before adding any tiles to the layers click on each layer in turn..... go to
*Edit Table .....
*Background ...... and click your mouse on a colour from the box.
Any colour at all because you will be covering it with a tile /foil / glitter anyway.
Then when you come to add your tiles you will find that it only fills the layer you are working on!
Much easier to see what you are doing.
