So this is today's creation. I kind of just wanted to try out wet moulding and my knife was a kind of simple enough flat shape to try it. It actually didn't go too badly, sure I could have done with better (and gentler) clips and a thicker, or at least less stretchy, leather but I think it worked.
The other thing that was new to me here is that I just freehanded the whole thing. I took some rough pencil marks and some rough measurements to start with but, having no idea how wide the front panel needed to be I just kind of glued it, cut it, stitched it, cut it some more, sanded and burnished it, all just freehand because I couldnt really get a ruler in there to cut against.
So yeah, rough as hell, misshapen in places and covered in marks and little mistakes but I kind of love it for that.
Pretty much, yeah. Soak the top one and stretch, smoosh and massage it to the object with a bone folder (I didn't have a bone folder yet so I just used some relatively not-too-sharp items I had laying around) then clamp it in place so it can't change shape and when it dries it will hold that shape. I kind of but didn't precisely follow this - https://mazeleather.com/4-ways-to-wet-mold-leather/.
