Stuff the Pillow ( You will need a certain amount of stuffing, more or less depending on how firm you want your pillow)
Stretch out and fluff up your to give it the square shape
Take your tissue out and lay it on a cardboard/other disposable surface
Pour a little drop(s) of your essential oil on the tissue
Open up your stuffing to create a place for your tissue
Put the tissue inside your pillow, in the middle so it doesn't leak out.
Cover up the tissue with the stuffing
Do a simple stitch along the top of your pillow-- in and out
Repeat step 8 until the top is sewn. If there is extra strong from the drawstring on the ditty bag, tie it in a bow.
