Long time lurker, time to get involved.
Still new to this, so I'm still trying to figure out how certain aspects work. I just recently finished a cell phone case based on one of George Hursts patterns. I made it, and then realized it was too small. I made a bigger one based on the size of my phone, which sort of fit, but still not quite.
My question is this. What is everyone's method for adapting/scaling patterns for things that aren't uniform size?. I;ve read plenty about how to do this with gun holsters, but that a whole different ballpark (in that there are SO many guns, it would be impossible to have a pattern that worked for them all). Cell phones are generally all rectangles, but are a little different.
Beyond the dimensions of an item (phone in this case, but I've had the same issue with knives) how do you know the amount of excess leather you need to allow for the thickness of a project?
