what can I use to cushion my knee when exercising with it on the floor so it doesn't hurt?
yes, a cushion, but every one I've found is too big and doesn't fir my backpack where I have more stuff (clothes, an umbrella...).
I like doing yoga and stretching outdoors, so the ground may also have loose dirt, broken pebbles and grass...
If I bend on my fours, raise-stretch a leg with the other leg's knee touching the ground to hold most of my weight with this leg's foot stretched to the back and still touching the ground, raise-stretching one arm and only using the other arm not to fall to the ground, the knee touching the ground hurts.
I've tried folding a small towel three times, but I'm so skinny that my knee still hurts.
Folding a yoga mat doesn't help either.
What works for you?

Gardening knee pads. Designed for spending hours kneeing in the dirt, and are flexible
I keep a pair of these in my car for dates
So instead of the girl tying their hair back, your foreplay is to pull on some kneepads? Hot.
I'm gay, in a county where most of the play is deeply closeted guys who can't host and want a blowjob in the woods. You kneel on a pinecone a few times, you find yourself investing in kneepads. Lol
Hardware stores might have cheap gel knee pads ($10 -> $40 for fancier ones)
There's also these kneeling mats / pads
Hunting/sports sections will have foam pads like these for sitting on while hunting/fishing or in bleachers etc. Have had one in my gym bag for years for knee-ground-exercise things.
Just search for "kneeling pad" or "gardening knee pad" and you'll find a bunch of pretty durable options for around $10. Or, hell, just get a pair of skateboarding knee pads. You might not be the pinnacle of fashion, but your knees will be well protected.
Google "Knee sleeves" literally designed for the purpose.
G-Form mountain bike pads would work.
You want the X3, not the rugged.

Look for a knee pad for gardening. Go to the gardening section of your local home improvement store. They're just big enough to kneel on. If that's still too big, maybe look for an inflatable camp pillow or camping cushion of some sort.
Swimming kickboard/flutter board?
Perhaps a soft kneepad that you wear would work for you
you could get a cheap foam thermal mat and cut out the size you need. beware though, as it will roll up by itself when too small.
True, but not everybody is built the same. I can imagine someone being so uncomfortable with it, that it would detract from the exercise..
I agree on the knee pad, but most of these seem a bit overkill. I'd go with a sleeve like this or a more lightweight knee pad like this.
They make thick pads for gyms that are designed for exercises where your knee is on the ground. I used them for a while
Depends on the type of yoga mat! Some are very thick, some are very thin. Sounds like you got one of the thinner ones. You couldn't possibly fold one the thick ones, it would open up on its own without a weight on it whereas the thin ones can stay as you leave them.
A kneepad is another option as many said already.
You also have mats for camping, my parents had a couple of these and they would lay them under the sleeping bags precisely to avoid feeling all the debris on the ground.
I just use my pillow or maybe a folded towel if I have to get on my knees for an extended period.
I use a large folded microfiber towel as knee support in pilates. It’s not as spongy as a normal towel but soft and supportive enough for those exercises that put a lot of stress on my knees or tailbone.
Hover your knee off the ground when you are in the all-fours helps. Like don't put your whole weight on it. Do poses that don't put as much weight on your knees. Look for better ground to practice, grassy areas.
When I yoga outside, it's the last suggestion I use the most. My knees are also sensitive, and finding a flat surface, then using my usual sorta thick yoga mat works well.
Rubber mat, like those rubber toy mats which can interlock. Or a workers knee pad, which isn't rubber as I recall, but another, tubed, soft plastic to coushion the knees. Pic related.
In my homegym I have an AbMat foam pad which I also use as a knee pad. And while I think the thick foam would work outdoors on tougher terrain, it would not meet your criteria to fit in a backpack.
My other suggestion would be a scrap piece of horse stall mat, which are nearly solid rubber sheets commonly employed for homegym floors. This is what I use when working in my yard, for tasks requiring a lot of kneeling. Such a piece -- while heavy -- could be cut to whatever size you need, using a sharp knife or a jigsaw.
