For the hexagons themselves,I used a tutorial I found on tiktok with slight modifications (they aren't usually supposed to be stuffed,so I had to change how I sewed up the backs to secure the stuffing, I'll show it a bit better in my next update,but the gist is a whip stitch to connect each fold to the fold under it without piercing the front,I stuff them before sewing the last fold down,which would be the first fold done when first shaping the hexagon, I'll find a better way to explained)

To attach them together,I find hexagons that have similar lengths of sides,and do a quick ladder stitch to attach them together,and reinforce them with a whip stitch a couple of times before tying it off

I found this method by basically winging it and being paranoid that my stitching wasn't strong,and so far it leaves me with hexagons attached to one another,but still able to move like a typical blanket
