Thanks for your help Barbara.
I have only had my copics for a few weeks so I doubt the lids would need cleaning yet BUT I didn't even know you needed to do that! I would never have done it!!!
Is there any sites etc, that you would recommend reading to learn this stuff?
I tried to find some classes near me and I couldn't, so I've just been looking at a few tutorials online.
I haven't found anything with this kind of info on it though.
And the card I'm using it x-press it blending card and I have seen a lot of people recommend and use it, so unfortunately I'd say it's me with the problem - not the cardstock.
