After starting to test out the whole wallpaper/pattern idea I realised the copies I was working with were pretty poor because they'd been photocopied then scanned so had lost a lot of the original colour, so I rescanned them all and started again.
I'm actually really pleased with them all and now it's just a case of playing around with adding text and deciding which one looks best. I'm really liking the chihuahua one just because it's like a proper pattern because they all sort of fit together. I don't really like the pug one. Also wondering whether to make the other ones smaller so I can fit more on them seeing as that's how the chihuahua one is and it looks the best. Thoughts?
