How to Sew a Reusable Muslin Tea Bag

Tea bags are tiny, but they are also a serious problem with landfill waste. Why not make your own reusable muslin tea bags so that you can enjoy better quality teas and go zero waste?

I love reusable tea bags because you can buy better teas (usually whole leaf teas or teas with whole ingredients) to steep. Which is so much tastier than the dried powder found in store bought tea bags.

Do I Have to Use Muslin?

No, you don’t have to use muslin fabric. However, many people prefer undyed muslin fabric because it is minimally processed and generally doesn’t have any added color or finishes that you wouldn’t want to brew into your tea.

Hemp is another fabric that would be great to use as it is made with less chemicals while growing.

Any cotton fabric will work. But make sure that it is free from dyes, colors and finishes that wouldn’t be safe to use in food. After all, brewing your tea in hot, boiling water is creating a product that you are ingesting, just like food.

Looking for organic, undyed fabric is the best choice for making reusable tea bags.

Should I Wash the Fabric Before Measuring?

Yes! Since this fabric will be put inside very hot water, as well as washed regularly, you want to wash the muslin fabric first before cutting. This is because some fabric shrinks when exposed to hot water. If you measure the fabric and make the tea bags without pre-shrinking the muslin, then your tea bag could keep getting smaller as it shrinks with washing. You will want to pre-shrink it, then cut the dimensions you need to make your own reusable tea bags.

Do I Need a Pattern?

Nope! You don’t need a pattern for these reusable tea bags. All you need to do is cut two pieces of fabric in the dimensions listed in the instructions.

How to Wash Reusable Tea Bags

Cleaning zero waste tea bags is as simple as tossing them in your washing machine and drying them.

You will want to add the homemade tea bags into a small mesh laundry bag so that they don’t get lost inside clothing or lost in the washing machine like socks do.

How to Make Your Own Reusable Muslin Tea Bags



Step 1

Cut two pieces of muslin to the following dimensions:

  • One 4” x 6” piece
  • One 2” x 2.5” piece

Step 2

Fold one 6” side under ¼” and press flat.

Step 3

Fold again, only this time make it ½” and press flat. Set aside

Step 4

Fold the top and bottom of the small fabric piece under ¼” and press. Fold from the longest side (the 2.5″ side).

Step 5

Fold the opposite sides under ¼” and press flat.

Step 6

Fold in half and clip to hold.

Step 7

Put the twine inside the folded part of the 6” piece of fabric. Clip to hold the twine inside the fold.

Step 8

Sew along the bottom of the folded edge that has the twine inside to form a casing.

Step 9

Fold the fabric in half with the right sides together and clip. If you’re using muslin, you might not have a right and a wrong side. So just make sure the exposed seam edges are outside, as seen in the picture above.

Step 10

Sew along the bottom and up the open side. Stop at the bottom of the casing.

Step 11

Trim the corner with a diagonal cut, making sure not to cut the stitching or get too close to the stitching. This reduces some of the fabric bulk to make turning the corners inside out easier.

Step 12

Turn the tea bag right side out. You might need to use a chopstick or turning tool to push out the bottom corner to be square.

Step 13

Insert ends of twine into the fold of the small fabric piece and clip together.

Step 14

Top stitch all the way around the perimeter of the tiny fabric piece to form a tab which resembles a tea bag tag.
