Fully embroidered with radial stiching, which is unique for a 3" version of this patch. Stars resemble the 4" A-B Emblem version. Very rough stitching for the sail shadows.
This patch was collected in a set of other 3" patches, also dissimilar from "original" A-B Emblem issues.
I am going to tag this collection with the "apollounk2" tag. Leading candidate is Cape Kennedy Medals based on the Apollo 17 patch in this set being a CKM patch.
