Very DIY mastering! I made no attempt to do anything fancy or different, just the original WAVs I mastered (I did use the 96kHz/24bit versions) for digital. It seems to come out really well to me (there is a sort of high end gloss in there, but otherwise just works).

You would probably get a better result even because you know what you're doing! The cut and quality seem really good - I'm not a big vinyl type and it's been a while, but they just feel like how I remember vinyl from years ago. Not flimsy lightweight, but not rock solid fat 78s style!

Print quality seems really good on the sleeves too...
