Reddit reviews Regency Wraps Set of 4 Bags with Drawstring for Enclosing Bulk Spices, Tea, Potpourri, Jewelry, 100% Cotton, 4 COUNT, Natural

Hi! If you want to get into tea, I would reccomend starting by watching Alton Brow's episode on tea here. It's a good background on everything involving tea and tea brewing.

If you have a Peet's Coffee near you, you can go and order mugs of tea (brewed with loose leaf). They will give you free hot water refills so you can drink as much as you can handle. You can find a tea you like without having to commit to a huge container.

I prepare my tea in the morning in a tea pot (I have this one, but I don't like it because it's hard to clean) and pour it into a travel mug.

They make travel mugs that are similar to a frech press (here) where you put the leaves and hot water in and just push down a stopper to stop brewing. I'm really picky about the lids on my travel mugs, so I don't own one.

For resusable tea bags, the most popular style is a [tea ball] (http://www.amazon.com/Progressive-Stainless-Steel-Mesh-Ball/dp/B00004RIZ7/ref=sr_1_1?ie=UTF8&qid=1407090137&sr=8-1&keywords=tea+ball) (although the one I linked is a little too small to allow the tea to fully unfold). They are cheap and fairly easy to clean, but you have to be careful where you store them so they don't get bent up.

They also make tea bags for loose leaf tea. These would be easy to pop into your travel mug. You can also find bags made of muslin that can be washed out, but I don't know where you would do that.

Why not try a spice bag?

You can buy these bags at gourmet cooking places

Initially, I was thinking about sachet bags, so that you could see the blend of spices. Also the drawstring is pretty cute. But not entirely sure I would use these to brew tea in due to not knowing too much about this organza material. Wiki told me it can be silk but could also be polyester/nylon, and I wouldn't want to heat those materials up.

Another possibility is cotton muslin bags. Not quite as pretty but safe to heat. Also seen here.
And some adorable DIY heart bags.

Cheesecloth bags would be good as well but the price is not so great here. I'm sure more googling would result in some better prices though.
Here are some homemade cheesecloth bags. Nice but not as clean looking as the other options. But I'm sure you could sew them up however you would like.
Martha Stewart does them beautifully and this site has lovely packaging.

Overall, I would probably want to make my own cheesecloth bags the Martha Stewart way because they look great while still being entirely done by you personally (and are relatively simple). Otherwise, I think that the tea bags terribletoos linked would be a great, safe, and cheap choice and then all the craft energy can go into creating custom labels and wrappings.

These are really cute labels.

Interesting labels. And then you could always create simple little packets/envelopes for them too :)

Edit: Organza sachets would probably be fine if it were clear to your recipient that they were not to brew in those bags, rather pour the contents out and brew loose leaf style.

How about a reusable teabag or even disposable tea bags? If you happen to live by a Daiso or other kind of dollar store, they sell disposable teabags for about $1.50 for a 100 pack. I think that there are also collapsable tea filters, if you don't mind a non-metal filter.

Otherwise, those are pretty small in terms of infusers (~2.5x4in) that would actually work well with tea. My last suggestion would be using a strainer like this although it's not too different from the second infuser I linked earlier (aside from maybe you could use this to scoop out the leaves). If space is the priority though, I think your teaball is already effective for your needs.

You can use a spice bag if the recipe has enough liquid to allow it to steep.
