I made this flag for my son. Yes, it is 3 FEET by 5 FEET. My letters were huge. My heat press is only 15 inches X 15 inches square. This was very tedious, but it was also fun. With the letters being so huge it was very easy to weed. I used Siser Easy Weed for this also. I did order the flag, but once I got it, I realized I could have just made it myself. the edges were just folded under and hemmed like the bottom of jeans, with a thicker material sewn on the side and grommets put in it. It would have been very easy, and probably cheaper to just make.
Thank you for looking!
