B-side quality means any of the following... slightly unevenly spaced serging, small fabric mistake (does not include holes, all flats with a hole will be separately mentioned in the description), slightly wrong size (anything over 1" will be mentioned) and/or other small things that to me do not look A+.
HumBird stretchy flats are made from 310gsm 47% hemp, 38% organic cotton, 15% stretch terry cloth fabric. This fabric is unbleached therefore contains colour variations. If you are uncomfortable with colour variations that can include darker spots. Returns are not accepted due to colour variations. On one side you will find a very soft smooth fabric and on the other side very tiny soft loops which give it the terry cloth name. The loops are very tiny and the flat can be worn with loops facing the baby or facing out. The flats are very stretchy and hook well to snappis, boingos, and diaper pins.
Flats are designed to be worn under a cover. Wool covers are my personal favourite and flats with a wool cover will allow your childs bum to breath and help keep diaper rash away.
Flats come in two sizes. After washing and drying they will shrink to the end measurements of:
Size 1 ca. 20" x 20" (50cm x 50cm)*.
Size 2 ca 28" x 28" (71cm x 71cm)*.
The final sizes are when measured from the halfway point. Final sizes can be expected to fall +/- 1". My final measurements after washing and drying were slightly larger than 20" and 28" respectively.
