I decided to make homemade envelopes, for an up coming project. I already had the scrap booking paper, I just needed to find a template. After looking online for a template, I decided that I would make my own.
I decided that there were two styles that would work out to be really easy for me to do. A square one and a simple rectangular one. The square one I made by finding out where the middle of all the sides were (I used 12"x12" scrap booking paper). Then I cut a small triangle out where the middle mark was. I folded in the corners to meet and used a glue stick to seal three of the sides.
For the rectangular envelope, I measured in four inches from the corners to create what would be the sides. I again cut some small triangles where the corners would be. I folded in the sides and then folded up the bottom. I cut the point off of the bottom in order to make it more like a normal envelope. Then it was time to glue the sides and bottom together. I also took a cup and rounded the point of the top of the envelope, to make it cuter (in my opinion).
A few things to pay attention to. 1- make sure all of your sides overlap. 2- I would recommend using a glue stick, and not liquid glue, so that the paper doesn't ripple (this just looks neater and I don't have all of the fancy scrap booking or paper crafting tools, I am not cool like that and I used what I have - cause I am cool like that). 3- Use a ruler so you aren't guessing. 4- If you are making a bunch of them, used your first one - that works out - as a template. This will make it go faster. 5- Make all of your marks on what will be the inside of your envelope.
