Obligatory plug for self-heal (prunella vulgaris)! It’s a perennial member of the mint family that produces pretty purple flowers that (according to my amateur observations) native bumblebees too large for clover can still enjoy! The plant is native to most (all?) of the northern hemisphere, and is unfortunately categorized as a weed by most lawn purists, which is actually just a testament to its hardy nature. Self-heal normally grows to about 1’-2’ tall, but can also handle regular mowing and some foot traffic, just like clover, making it a great lawn additive or border plant.
EDIT: I get it, the consensus is that this is incorrect. I retract my statement.
Surprised no one has said this yet:This happens when you put zip-up clothing in the dryer. The fabric shrinks and shifts but the metal/plastic zipper doesn’t, creating a size mismatch that results in a bulge. Hang-dry your zip-up hoodies instead. I have hoodies that are close to a decade old and still haven’t begun to bunch up because they’ve never seen the inside of a dryer.
