Sounds like you thinking of making some sort of carpet, like used indoors.
That's good for not leaving a footprint and in a regulated area.
Consider taking advantage of the natural environment and adapting to it.
For a ~3 meter radius Circle
Scout and clear a suitable area for your standards.
Equip yourself with 17 Stakes, Hammer, 1 Spool Non-stretchy String, Tape, Scissors. Stake the center with magical intent, tie string to center stake in a way that it won't wrap around the stake or loosen. Size radius of circle toward a cardinal point. Mark length with tape and cut string with a little extra to hold onto. Stake it, then stake the other cardinal points to the same mark, then crossquarters. then finally stake between the quarters and crossquarters.
...and then?
That's for you to decide. In some places with taller grasses I like to stamp down the area in the circle through ritual movement for establishing the space. Not scorched earth destructively, enough to subconsciously pick up the physical boundary by what's obviously walked on. That also means taking some care on where casual walking takes place, but that's part of making the space particular. Afterwards might take a season to completely disappear. But do clean up afterwards. To my shame some of my early circles I've gone back to I've found rose stems from rituals performed years earlier.
For the Holy Names, if they need to be written, you could write them on preprepared objects, fabric, or paper devoted to them and secure them around the Circle in the way they need to be placed.
