Best pen for drawing on window designs

[Flowerpetal2]

We have bit (new) sliding doors. I’d like to do some Xmas window art this year but not sure what pen to get - chalk? Window pen? Something easy to clean!

POSCA paint pens just wipe off, we use them every year

I came on to say Posca too.

The trick with Posca removal (as it will dry on and be a bit stubborn) is warm soapy water and a the non-stick scrubby side of a washing up sponge. They are the best though. I'd go with a 5mm for most lines (good from a distance), 3mm for fine bits and a chonky flat edge one for infill. Good luck!

Any acrylic pen (like the ones mentioned above) will look the best..

They come off fine, but its a 'job', not just an easy wipe-down after as it would be with simple water-colour markers.
