What you’ll need:

Cotton scraps. Other natural fabrics can work as well but avoid synthetics as they can melt in the oven.
Beeswax pellets. I’m using a standard organic Beeswax made in the US, if you don’t like the smell of beeswax you can get a cosmetic grade that
Baking sheet
Parchment paper
Scissors
Old Brush that you won’t care if it gets ruined
Oven or toaster over

Optional

Step 1. Prep it!

Preheat the oven to 175℉ and line a baking sheet with parchment paper.
Cut your fabric into squares or rectangles of whatever size you want your wraps to be. If you plan on sewing a pouch after you’ve waxed the fabric make sure to cut a rectangle long enough to form a bag to hold your snacks.

Step 2. Wax it!

Lay your fabric on your lined baking sheet and sprinkle the beeswax over the fabric. It’s better to be generous with the wax because you can always reuse the excess wax and it’s just annoying to have to repeat the melting step if you didn’t get enough coverage on the first pass.
Put the pan in the over and set the timer for 10 minutes. It may go faster and it may take longer depending on your oven and what brand of wax you’re using so check in periodically. When the wax is melted remove the pan from the oven. Using a brush, spread the melted wax around the fabric making sure that it’s evenly coated with a thin layer of wax. You don’t want to have too much wax on the fabric as it could crack and be crunchy rather than flexible.
Peel the fabric off of the parchment paper and let it hang to cool and drip dry any excess wax off. Make sure to hang it somewhere that you don’t care if a little wax gets on it.
And that’s it! You’ve made a wax wrap!

** Alternate Method **

If you don’t have or care to use an oven you can use the ironing method. Set your iron to med-high to high heat. Lay down on old rag that you don’t care about getting waxy on an ironing board or heat resistant surface. Cut a piece of parchment paper at least double the size of the fabric you’re making a wrap of and lay that on the rag. Lay the fabric on parchment paper and sprinkle beeswax on the fabric same as above. Fold the parchment paper and the rag of the fabric so the wax and fabric are sandwiched in the middle. Press down with the iron over the full fabric area being sure the wax is fully melting. When the wax if fully melted peel from the parchment paper and cool as above.

Step 3: Pouch it!

Cut several strips of parchment paper roughly 1 - 2 inches wide.
Using a rectangle of fabric that you’ve waxed and cooled, on one of the short end fold back the edge about 1/2 inch. Wrap the edge in parchment paper and sew the folded edge using the edge of the presser foot as your seam guide. Trim the excess treads and peel off the parchment paper. The parchment paper helps to move the fabric through the machine and keeps the wax from catching, if you have a walking foot you may not need to use the paper. Your call.
With right sides of the fabric together fold the finished sewn edge up about 1/3 of the length of the rectangle. Wrap the edges in parchment paper and sew from the finished edge down to the fold line. Trim threads and remove parchment paper.
Turn the pouch right side out making sure to turn the corners out to a clean point. Using your hands, press the pouch flat. You can stop here if you want and your pouch will function just fine but I like to sew a little more to clean up the edges a bit.
Fold the edges of the pouch flap (the part we haven’t sewn yet) in about 1/4 to 1/2 in. Wrap all sides except the bottom of the pouch with parchment paper and stitch the edges.
Trim all the excess threads and remove the parchment paper

Step 4: Snack Time!

Wash the wax off your hands and give yourself a pat on the back! You’ve made some lovely sustainable wraps protect your snacks from the elements!
To clean the wraps, use cool water and soap (Hot water will melt the wax off the fabric). Let air dry on a rack or pat dry with a towel.
If after some use you notice the wax has worn off, to refresh the wrap simply repeat the waxing process.
