That's adorable. Criss cross stich spider nets onto my car all the time because it's parked quite close to the garden, and I think they generally sense/smell me on it. Then there's 1 giant buddy 🕷️ who lives on my windshield somehow (always appears whenever I clean it). Even if the car goes into a wash machine, dude knows how to enter the car and come back out unscathed. Had some bad incidents too, but generally trying to reach an understanding with them - the house is theirs after midnight. They do their thing. During the day, they hide well.
