You might do what I did when I was a kid. Go into the back yard with a tarp, a hank of line, some poles, tentpegs and go for it. I must have pitched my tarps, ponchos and army surplus pup tent a thousand different ways.
One of my favorites for many years is what the old Scout Books called a "Trail Tarp". A chunk of fabric about 8 or 9 feet square with a set of ties in each corner, three between 'em on the sides, one in the center, and one midway between the center and each corner for a total of twenty one. My Mom helped me sew my first one out of unbleached muslin. I treated it with some kind of waterproofing crud from the hardware store. I put grommets in it, a mistake. After they tore out, I sewed in ties of lightweight cotton webbing.
That tarp taught me the necessity of a good steep pitch to a cloth shelter by the simple lesson of waking up sopping wet in a light rain. I also learned about seams aligned like shingles so they shed water. I played with that thing in the back yard for many hours pitching, then testing it by setting the lawn sprinkler nearby to see if it stayed dry underneath. Doing that also helped me learn the quickest pitching method for any given scenario. I carried my tarp in the Cascade Mountains for many years. In later years I found it's descendant in the Campmor catalog, made of coated nylon and priced at nearly $50. Even at that price it's a good deal. Not PC by any stretch but a good lightweight shelter.
6x10 is a tad smallish in width, but will work. I'd put ties on the long side where the short side folds square to it, that will make pitching it as a diamond much less hassle.
Pitch it then cut a ridge pole to fit. After that pitching will take only a few seconds. A "jill poke" or slanted upright made to fit under the ridge will make it much more stable.
My favorite tentpegs are 3/8" x10" or 12" spikes. They cost less than half a buck each, are unbreakable, and being round don't cut peg loops or guy lines.
