Hello. I have a roof terrace with a roughish stone floor and wanted to lay a 8ft by 8ft square of astroturf, but the softer stuff for my baby to play on. But it's quite expensive s I don't want to eff up and buy the wrong one. Any recs or things to bear in mind, and anywhere good to get it (have seen some offcuts on ebay, but it's still expensive).
Cheers.
