Reusable Nursing Pads Set

Mismatched reusable nursing pads. Others seem to have been lost in the wash. 1. Homemade. Unsure of fabric but seems to be a cotton knit. 2. Homemade set. Yellow side is silk (inner / skin side). Maroon (outer) side is wool. 3. Unknown brand 4. Lansinoh. Three are 3 of these. I found a set after taking the pictures.
