Sorry, I couldn't resist the subject line.
I'm getting some patterns ready for my first pillows. I've looked at what others have done here, some great designs. My problem is I can't find information about actual pillow construction as it relates to the sizing of projects. In other words, if I want a 20 x 20 pillow, obviously I need a larger final piece of cloth to allow for seams, zippers (I'm using buttons for mine), and other items. Plus, should I weave the back immediately after the front, with no gap between the two? I will not be sewing them, they will go to a seamstress. She may have the answers but I thought I'd check to see if there's any special weaving requirements I need to be aware of before embarking on this project.
