This is the book I referenced on this weeks Crafter Gathering last Wednesday night.  I recommend looking for used copies online if the Amazon one is too expensive. I haven't made any of the patterns out of it but I have wanted to.  It calls blankets rugs, and one of the blanket patters are a group of tunisian in the round squares - this uses a double ended hook to do tunisian in the round.  I've made a few squares from another pattern and a cowl in tunisian in the round. I'm still learning it.

This is the kit on Amazon which I mentioned that has ergonomic handles for the thin small steel hooks. This set has the hooks sized (0.5mm - 2.7mm) Tulip seems to have a set too but they are pricey, clover has one but they don't go down so small. They also have other sets of these ergonomic steel hooks with or without cases too on Amazon https://www.amazon.com/gp/product/B0BCPY72NB/ref=ox_sc_saved_image_10?smid=A8XDZQ03DWTEL&th=1

Today's stitch was the feather stitch I had made a feather stitch blanket during from a free pattern that was released last year for a blanket drive for Warm Up America. I didn't finish in time to mail it off and really loved how pretty the blanket came out so I decided to keep it. I may gift it to a relative but I still haven't decided yet.  I was thinking folks might want to see a picture of it and I can share it here.  I used Lion brand pound of love, one skein of each of those colors I think if I recall correctly.  The pattern was a free pattern with video tutorial.  If anyone wants the link please let me know and I'll look for it. I can also look for the colorways as well if anyone is interested in using these same colors.  This stitch is a yarn eater and the blanket is definitely heavy, weighted blanket and it's nice and squishy.
