Thinking of starting another collection, but don't know what to collect. Suggestions please?

You could start with insulting replies to this post.

Another collection? What do you collect now? (or is there a clue in your name?)
How about insect samples, pinned to boards? Easy to display…

Asking questions like that, on a Sunday morning…

You might want to start with collecting notches on the bed post.

FWIW I collect clockwork toys and Beatles picture disks.

collect bikes?

[plenty on here do!]

Prostitutes bodies

I've been meaning to start collecting money (stirling) but it is proving surprisingly difficult! 😉

Etchings.
Then when you invite ladies back to look at your etchings they think you are a sincere and trustworthy person.

If you've got to ask what to collect, you're a bit of a lost cause really. Most people seem to collect things because they like them and/or have n interest in them. Asking what to collect seems to negate that basic interest.
