okay let me back up a little bit. LisaAnne, I'm glad you're enjoying the challenge! Crispysoap, coolsuds, and Deeanna, thanks for the kind words about the video. Rowan and dibbles, I'm so sorry for your mishaps! It happens, believe me. I bet they'll be lovely in spite of it.
Rowan, if your mold seems to be a little bit shallow (slightly shorter like my crafters choice is in the video) you really need to make sure you hit that back corner, or even go slightly above that back corner, because it might not leave enough space at the bottom to really lift your wall pours up. If you have a mold like my one pound mold, as I showed in the first video, that's slightly taller than my Crafters Choice mold, then that back corner is going to be fine. If your mold is maybe a little bit taller like a custom mold, like a centimeter or quarter of an inch or something like that, then if you don't quite hit the back wall it might work out. It's going to be really geared to the size of your mold, and I found the back corner works well. If you find it wasn't enough batter you might go a little bit further than you did previously on that try. It's gorgeous as it is btw!
for what it's worth, I did not hit the back corner on one of my practices in my square one pound mold. It wasn't enough. So as I said if you have a custom mold slightly taller that might work out. Slightly shorter go a little above the corner, about standard sized, then the corner works great. this is one of those challenges where I think the size your mold is going to really determine how your design will work out. So it's going to be something you need to try once, and if it doesn't work out maybe make a little adjustments with it on your second try.
Amd, yes, long side
Misschief, cool effects! Sorry it didn't work out, but it's cool nonetheless!
