It's hard to tell you a specific place since the type of furniture varies.. but try taking a walk @Downtown and checking out the antique stores there am sure you'll find a lot
It depends on what type of furniture your looking for (oriental or eastern etc) but check out @Ali Baba Cave or @Rihani Gallery.. there is also the option of walking around @Downtown and checking out the random stores there :)
@Al-Balad - You can start off here by just walking around and discovering all the small magnificent corner shops and beautiful markets. Lots of nicknacks, books, pictures and bizir shops :) (my favorite to buy is mlabbas il malek hussein). There's a bunch of restaurants too (Hashem, Abu Sara, Zorba, Jafra) and of course Habiba for Knafeh! In the winter time you can hit up some delicious Sahlab to keep you warm, and continue discovering. There's lots to see and learn from a trip downtown and if you guys are fit and like to walk(this is more like a mountain climb) I suggest taking steps up to Jabal Weibdeh and check out the scenery, galleries, and some of the churches up there too. This is my ideal date! I ended it at Canvas Restaurant (Duwwar El Muntazah also in Weibdeh) where I had a lovely pizza and some local wine, then got to catch a beautiful performance by a live jazz quartet (they don't play every night though). I really hope you try this out it's awesome! But beware you will be exhausted by the end of the night.
Tip n' Tag did a blog awhile ago about DIY stuff, with the link of craft stores, here is the link http://blog.tipntag.com/the-weekender-lets-get-crafty/ also honestly @Downtown you can find so much stuff, but it really depends on what you are trying to do.
Well i actually like walking & taking pictures @Downtown as well as @Jabal AL Weibdeh, i also like taking pictures outside Amman at @Fuheis Madaba & the dead sea as well, you can take great photos there
You have so many choices; you can either go to a park spend a good day there such as @Al Bahath Park , or you simply can take a nice walk at @Downtown or Jabal Amman you can find there so many touristy shops
