If at first you don't succeed, try...
Ha HA! Guess what? Those coasters are fixed.
Lots of patience and loving kindness went into the re-sewing, and I'm pleased with how they're going so far.
There are only a couple of downsides as I see them at this stage.
(1) It is possible that some grumbles and eye-rolls pushed past the loving kindness and made their way into the do-overs. (Oh, gross. I didn't mean "eye-rolls" like "egg rolls". I meant it like... you know what I meant. Eye rolls would be disgusting.)
(2) Matthew commented that he likes to have the coasters split open so that guests can enjoy the stuffing as an appetizer. These sewn-up coasters mean the parties are gonna be B.Y.O.-stuffing if that's your thing. Sorry, Matthew.
There are still quite a few coasters left to make. But, this being the second time I've made them, I'm now more sure than I've ever been that there's no! way! I could "make these the day of the party", as Purl suggests. How would that even be possible? I don't know.
What I do know is this: Do-overs are a glorious thing.
