Antares, what excellent advice, and I will take it! I think I'll make the insert first, then attach it, as you suggested. So all this helps with my thinking more expansively, which is good for any creation! And I am going to be meticulous as to gauge-as I said in my first post I'm a newish knitter, and gauge is intimidating territory for me, but I've researched and found a few formulas that I feel will help. Thank you so much for your advice

Really thanks to all of you who came here to help me and inspire!

Y'all are good people.
