I'm confused (it doesn't take much ) but your asking for info about Maidstone, Kent but your location is down as USA on your profile. I don't know what made me think to look...I guess I've only really realised recently how many US cities and towns are named the same as UK ones so I thought I'd check I was understanding you correctly...or you can just call me nosey
Anyway - I don't know of any stores there but if you try the UK scrappers forum you might have more luck finding someone more local. Also there's lots of good online stores - at least there was when I used to paper scrap not so long ago! Good luck!
Definitely try out UKScrappers forum - it is loaded with info and they can point you in the right direction there. I go there whenever I am planning on going to the UK to find out what's new etc and have used their advice.
I have also found some shops, clubs and events all around the UK. I am not sure if it is okay to post this information. So please feel free to send me a message or if a moderator could let me know that it is okay to post the information I will.
