Well, this is KIND OF AN ANSWER to your question about EPP - kinda not! LOL!
Yes, i have done EPP mostly hexagons. I buy the precut shapes. I mostly have done little made up projects so far. BUT… when the New Hexagon Millefiori by Katja Marak first came out i bit - AND BIT HARD! LOL! Oh yes, i ordered the book, calendar, and all the tools and signed up to have each months EPP kits mailed to me so that by the end of the year i would have everything i needed for someday in retirement when i finally had the time to do it. I even found a project bag big enough to hold everything i might ever need to go portable 🤩 but i havent started it YET. But hoping to by the end of the year.
i have done both thread basting and glue basting. I do like the glue basting, but as has already been mentioned you dont really want to use the glue and let the project sit long term.
