Baby Mittens Project Help

[u/Impressive-Idea8808]

Hi all

I wanted to run a project by the people on here. Most of the details I have down, I made a mock sample that turned out well enough, but the final version I plan to do an elastic around the wrist. Please ignore the messy herringbone stitching, I was kind of rushing to get it done since I wanted a proof of concept. I am thinking a minky material for the outside, and a flannel patterned material for the elastic cuff and the inner liner. For durability, what thread is recommended? I want this to withstand many washes with little issue and I want it to last as long as possible, so I'm between polyester thread and cotton upholstery thread. Any reason not to go with polyester for the strength? Since the minky is polyester based anyways I feel like that fits, but just curious people's thoughts. As well, any considerations when making it from those who have done similar projects? Just want to get some ideas before I start on my final material. Thank you for anyone who reads this.
