Live and learn. I've tried a number of tricks and techniques over the years and most of them turned out to be bad (or at least ineffective) ideas for one reason or another. But some of them have worked out well and I continue to use them to this day. Keep experimenting.Thank you for your detailed observations.
Apologies for my sloppiness, the colours seemed a good call but now you mention it, it'll prove troublesome in the future
As for the sloppiness, that's not unusual. Deal with it now and you can save yourself LOTS of grief down the road. Otherwise, you will deal with it after you go through lots of grief down the road. Either way, it's almost certain that you WILL deal with it.
