My Sister sent over some templates for envelopes with a note that said she didn't know how to use them. So here is my photo montage of how to use an envelope template: First of all, let's pick out some pretty paper. Mine came from a stack of paper purchased at Michaels' in the clearance aisle. Two pages out of the stack were damaged, but at 60% off, I could deal with that. I put the template on the paper, positioning it where I thought it would look best. Then I drew around the outline of the template with a pencil. Why pencil? Because you can erase the marks later. This box template, as I look at it will have a sort of triangular shape. It will be long and have a very narrow bottom. So I traced around the whole thing, leaving out the parts in the middle. We will get back to those in a minute.

That's called,"Antibiotic Resistance" a once-potent antibiotic is now freaking useless to that bacteria. How doe...
