On Sunday late afternoon I made 2 wheat packs !
I used calico fabric and added 1&1/2 kilograms of wheat in each one with a few handfuls of dried lavender. I will make covers for them , like little pillow cases that can be taken off and washed.
I made them larger then others I have seen for sale, mine are 26cmx34cm. I like the idea that you can remove cover and wash it. I've never seen them for sale with removable covers. If you ever purchase them you could sew a small pillow case cover for it to save getting it dirty .
When I make the covers I will take a photo and post it so you can see them and if anyone needs instructions to make them I will also post . They make great gifts especially this time of the year, well really any time they are great also for aches and pains .
