The Stamp-a-ma-jig is a great tool. It helps you to line up your stamped image. So if you are a crooked stamper maybe it's time you invested in a Stamp-a-ma-jig (SAMJ). To start stamp your main image.
The SAMJ comes with an imaging sheet. It is a clear plastic sheet. It is really smooth on one side and slightly textured on the other. You should use the smooth side for inks such as StazOn so that it doesn't stain your imaging sheet.
Line your imaging sheet up with the inside corner of the SAMJ.
Then take your image stamp and line it up with the corner of the SAMJ and stamp onto your imaging sheet.
Next, line up the imaging sheet with your stamped image where you want it. In my example I wanted the pumpkins in the back of the truck.
Then realign your SAMJ with the imaging sheet.
Remove the imaging sheet and again line up your stamp in your SAMJ and stamp.
My pumpkins are perfectly aligned with my truck.
Finish your project.
I hope I didn't confuse you too much or scare you away from using the SAMJ. It really is an easy tool to use once you get the hang of it.
