Very Theraputic Might I Add(✿◡‿◡)
Needle and dry felting mean the same thing.
Sewing needles are straight to slip right in and out.
Felting needles on the other hand are more harpooned shape.
-To REALLY dig in there. wool or meat otherwise.

Some people call these "soft sculptures" but I just prefer the word felting. Yall gonna have to get used to that word on this block.
