Is there a standard size for a folded t-shirt? I want to build a DIY shirt folder, but not sure of the size. An XL folded to 9X12 looks about right. What do you suggest?
Google Flip and fold and you should come up with it. Also check Youtube as some have posted videos of their homemade shirt folder.
I use two scrap pieces of cardboard taped together and cut so that it fits inside the shirt bag. This way you can stick the folded shirt & cardboard in the bag, then pull the cardboard out and the shirts stay. Seal the bag and ship.
If you will be displaying them then you may want a better folding system so they can be neater.
