Excellent! How did you do the hat?
Honestly, I just ripped both images off the 'net, and opened them both in GIMP - on separate layers. I had already gotten rid of the unwanted white background on the shield image some time ago, but realized I had removed just a small bit of the upper right pointy part. So back to square 0.
Then I rotated and positioned the hat using the shield part as a reference, and used round brushes with the eraser tool to get rid of the part of the brim on the hat that's "behind" the shield part.
Then I double checked with Inkscape (The images display a little differently in the 2 programs.)
