Halloween Costume using stuff from home?

Ok it is that time of year, finding Halloween costumes. The thing is I don’t want to buy a costume. Does anyone have ideas for costumes we can make using stuff at home?

There is the tradition grab a sheet and cut wholes.  Thing is… I don’t have white sheets and I probably wouldn’t cut holes in them.

I have some canvas type material that might be good cut in strips for a mummy…

My 13 year old has a suit, she could be a lawyer or executive time, maybe a zombie in a suit.  But I am not too into scary stuff.  Hmmm

One year I dressed my son up in his flannel shirt and put his tool belt on.  He was a construction worker, it was sooo cute.  Would have loved a pic of that!

One year I dressed my ballerina in her little leopard outfit and just colored a nose and whiskers on her face.

Any ideas? I would be most grateful….
