Thistle Needles are not something Grounded 2 will direct you to obtain in the beginning. However, if you're an archery enthusiast (read: too scared to melee), you'll need this material by the dozens to craft arrow bundles. Since the game doesn't exactly explain where each material is found, its apparent scarcity can throw off a lot of players.
In reality, Thistle Needles are quite easy to farm in Grounded 2.
Where to farm Thistle Needles in Grounded 2

To get Thistle Needles, you must find and climb the stems of purple flowers. There are a lot of these scattered about the map, including a bunch of them in the opening area (that is, near the Snackbar). In fact, if you exit the Ranger Station (through the side where you can see the Resource Analyzer), you'll see one purple flower in the distance.
Otherwise, the map of Grounded 2 itself makes it easy to spot these locations. If you look closely, you'll find a lot of purple dots on the map. Simply waypoint (default keybind on PC is T) to mark one of these, and then find your way there.

Once you do spot one of these plants, numerous Thistle Needles will stick out of its stem. They can be found throughout the length of the stems, and there will be convenient rows of leaves sticking out, allowing you to climb it as you collect all the needles.
All in all, it's easy to collect oodles of Thistle Needles in one climb of these purple plants. Plus, to make things even better, they respawn as time passes - so setting up camp in a walkable distance of one of these plants gives you a replenishing source of arrows.
How to craft bow and arrows in Grounded 2
Once you acquire a bunch of Thistle Needles, arrows can be crafted by hand. Each bundle contains 10 arrows, which takes the following to craft:
- 2x Mite Fuzz
- 5x Thistle Needles
So, in other words, each Thistle Needle roughly translates to two arrows. You can also retrieve arrows after you kill enemies with them (or even if it whiffs and sticks into a surface somewhere else), so the ammo economy is quite sustainable.
