How To Do Very Basic Stuff?

[abrogard]

I need to make a page of traceable letters for children to trace over, you know? To learn to write.

We have a sample page but the letters are too big and too much space is taken up by unnecessary drawings.

So we just want to extract the letters and resize them and fill a page with them.

Simple?

So they're conveniently in two separate rectangles so all we have to do is select the rectangles and copy them over to a blank page.

Then we can resize them and then copy them over and  over until the page is full.

Trouble is we can't get past the beginning.

We select one rectangle of letters and copy it.

Then we have opened a new blank image and we go to it and paste the rectangle into it.

That works fine. Seems to.

But when we go to copy the next rectangle it just doesn't copy.  

A blank rectangle turns up.  Nothing in it.

And when we think ahead a bit and try moving the rectangle we've got around the page it doesn't move.

We're doing something wrong and this is presumably about the most basic of all things you can do - cut, copy and paste.  Move things around to fit together.

Can someone help with some instructions on what we should be doing to get this done?
