I have been able to make a block repeat and a half drop repeat for my wrapping papers. You might notice a cheat at an all over repeat too, I still find them difficult so for now I have placed the images individually on the canvas. Now I'm completely converted and I love photoshop! Once you can actually do a few things it makes everything so much quicker and although I'm not specialising in print I do enjoy making prints on photoshop.
I have now finished my card project except from a few finishing touches which will be completed once I go back to uni in the new year. So now I have the holiday to do what I like and I've started by trying to re-organise all my stuff and declutter, there is a lot of it so its taking quite some time!
