I made it with pure linen fabric for the pillow cover and lightweight cotton fabric for the inner pillow. I always try to use inner pillows for my sachets because the perfume of lavender buds tends to fade with time and an inner pillow allows you refresh your sachet with fresh lavender quiet easily. It is also useful if you need to wash the sachet for some reason.
This sachet has a simple envelope closure.
I gave it as a Christmas gift to my mother, but I am going to make some more similar items for my Etsy shop.
