In a way to reduce the amount of plastic we use around the home I have been looking at ways to swap from the plastic zip lock lunch bags to a more environmentally friendly option. Our first step was to reuse the plastic bags where possible by washing them, not always a fun task. Another option was switching to the humble brown paper bag, however this was still a disposable alternative. I was wanting a reuseable product that was easy to use. I had my eye on the Biome sandwich wraps and have popped a few on my wish list.

I then stumbled across Frugal and Thriving’s two posts (here and here) on free bag making tutorials. I spotted the Sandwich bag tutorial and thought to myself I can do that. Mum had some fabric I could use including some rubber backed upholstery fabric swatches. Over the next two hours I whipped up a very impressive DIY lunch bag.

You will need cotton fabric for the outer material, nylon fabric for the lining, and a sewing machine plus sewing accessories.

1. Cut a rectangle from both the cotton and the nylon fabric.

3. Create a box corners on both the cotton and nylon fabric by folding each corner into a 90 degree triangle and sewing across the tip. Cut off the excess leaving a seam allowance.

Finished product!

I did not follow the dimensions in the tutorial as my size was dictated by the size of the pre-cut swatches I had for the inner lining. Note to self: rubber backed fabric is difficult to work with, especially if you are new to using a sewing machine. Husband was so keen to use them after they were made I had not even had a chance to pre-wash them (don’t worry I didn’t let him use it till it was washed). Please remember these bags are not watertight or waterproof.

Now all I have to do is make a few more lunch bags and perhaps play around with the dimensions to create different sizes. I still have some rubber backed swatches so I may go looking for the Green Lifestyle Magazine I have somewhere with the bowl covers tutorial. Keep you posted if I find it!
