Do you have projects that you keep coming back to? I just looked at my notes and the first time I tried this pineapple mini was in 2010. I got it out a second time in 2014 with only slightly better results. I recently tried again, but this time I actually bought the ruler. It's amazing how easy it really is, once I stopped fighting against buying yet another ruler. I know it's an oft repeated cliche', but the right tool for the job makes a difference.
Now all I need to do is figure out how to miniature-ize it. ;)
