Pram liners

[SupermarketSweep]

I need a summer one because the one I have is really thick, ok for now but I think dd may get too warm when if it hots up.

Can anyone recommend a place to buy from? I have seen a few groups on facebook that sell customised pram liners for specific prams dont know whether to bother with a fitted or one or just get universal.

Also.. What print will shall I get? So many to choose from, my pushchair is a bright red colour want something to match but nothing minnie mouse etc

Any advice welcome
