They don't give you enough! Can you order more or do you just have to use the plastic tag things instead? Sorry to be a pain and ask all these questions. Promise when I'm an experienced piggy mum I'll leave you all alone! :x

Thats just the first one that came up in google. I know theres loads of links around here for grids, if you go to the sites that have the grids usually they have an option for extra connectors if you buy the grids seperately
Well the ones that i got with my pack are the ones for 14c on the right hand side of the top row? Maybe you got different ones?
