I got the 9x12 version of [https://www.amazon.com/dp/B004303ZGY?ref=ppx_pop_mob_ap_share](this one) to go under our canopy and we were very glad we had it! It feels a little nicer and homier than a tarp and it has loops to stake down the corners so it stayed put all weekend. If you have the space to pack it I definitely would recommend.
