My mom’s computer is an odd shape so she wanted me to make her a laptop bag. I spent forever trying to figure out how to make the expandable pocket for her giant power cord, and I think it turned out pretty neat! Since I didn’t have a pattern for it, it was quite a process trying to figure out how to factor in the size and the seam allowances and I also didn’t actually have the laptop so that made it even more of a challenge. I’m glad I finished it, and now that I figured it out I think I might try to make one for myself with a zipper. The only problem is the webbing handles catching on the velcro, so I might try to cover the handles some how…
Twill tape. You could try twill tape or grossgrain ribbon over the handles. It might still get snagged but it might not. I took an ikea blue bag and put velcro on it to keep it closed and the yellow thread from the wores IKEA kept snagging in the velcro too. So I took some twill tape and sewed it to the back of the handles and shazam. Beautiful bag by the way!
