This is another software programme, that can be used in your card-making.... and it's free!! Yaaaay!
I am a reletively new user of this programme, so I am still learning too. But it has lots of online tutorials for you to follow, that will give you all the guidance you need.
I use this to edit the photos I need to upload to this website and it's very easy to use.
It has a design element to it as well, so if you wanted to try designing your own papers then give this a try. It's got to be worth a go if it's free!!
Take a look, the link to Gimp opens in a new window.
Come back to me when you've finished.
