Bright yellow flannelette is the fabric backing of these ones.
(The fluffy flannelette goes against your underpants and the smooth cotton top with the curvy core stitching, goes against your body.)
Light pads have one round of core stitching (the curvy core stitching on the glitter print holds the absorbent core in place. So you need to have the core stitching against your body).
These are designed for light menstrual use (start/end of your period, with a cup or tampon) but are thin and comfortable enough to be used for daily use as well. I have found that these sit perfectly in wide gusset undies such as Thunderpants.
They are approximately 20.5cm x 15.5cm.
Pattern placement will vary.
When they are new, try to keep dark and light colours separate and the red flannelette backed ones separate from lighter colours for the first few soaks and washes.
I put mine straight into a bucket of cold water (the liners that I wear daily just get bunged into the washing pile. They don't get soaked unless they are used for my period).
When I have enough to wash I put them through a rinse cycle and then wash them with my other washing (on a cold or warm wash) and then hang them out to dry or put them in the hot water cupboard.
If you get stains, you might like to soak your pads in product such as Ecostore Laundry Soaker and Stain Remover.
Unfortunately most homemade washing powders do not have the enzymes required to break down blood. You will need to use a bought washing powder that contains them. I have used Ecostore , Earthwise and Surf, all with success.
Do not use fabric softener as it can make pads less absorbent.
Do not use bleach.
Do not tumble dry
Do not dry clean.
Fading and pilling of the fabric over time is normal and not a defect.
If you want your pads to remain bright and vibrant, do not leave out in the sun for long periods of time.
