Seasonal ambition re: slug draft stopper

We had one cool day and I am having my traditional seasonal ambition to make a draft-stopper for the one drafty door.

I have already made unprecedented progress by choosing a design and even buying a pattern, because how could I resist this perfect soft sculpture of a slug by Clare James?

Photo of a large greige corduroy slug perched on the back of a couch against an off-white wall. The slug has a realistic shape, with a mantle and four eye stalks. The couch is covered in a green patchwork quilt and cushions with earth-toned prints. There is an abstract blue and orange artwork on the wall above.

Inspired as always by my friends’ projects, in this case a pal who made this sardine as a draft-stopper for her mom who loves tinned fish.

Now I am torn between using generally sluggy fabric I already have, or buying something to make a perfect banana slug 🍌
