Sorry Nana, I didn't see this post until today!
I have Helena's breakthrough's and see includes a really neat how to in a .jpg form called: HelenaJole_Breakthrough_Directions.jpg look for that in your folder and open it in PSP to view it!
However we don't really have clipping masks in PSP so what I do is to lock the paper layers (the little padlock icon) you wish to fill with another color or pattern.
These would be the: Top Paper and the Paper Underside layers.
Now you can use the bucketfill tool to fill in another color or if you have a paper open in PSP you can also choose that in your materials palette and then bucket fill that in also.
Hope you see this!
