I like my small leather goods (SLGs) especially my Louis Vuitton: wallets, key holders, coin wallets. But, i wouldn't say i collect them. I have my set number of SLGs that i use everyday. So, whilst i guess it is a collection; it isn't something like my jewels where i have multiples of RHR and rotate them around.
I collect and use my bling lapel pins/ boutonniere. I have several of them now. I have reached my limit in that dept, so as they get a fair share of being worn! LOL...
I love scarves and gloves. I have quite a few; though not in the luxurious (LV Hermes etc) range.
I love watches.... have 3.... JLC reverso duo, a swatch, and recently acquired vintage Rolex.
I am sure there are other things i collect but i can't think of them right now.
Shells from travels. Christmas ornaments from travels too. There's something about looking at the tree and getting glimpses of places we have been.
and unintentionally, bicycles.
