These handles are truly great, no need for any interfacing, rope, tubing or similar, just vinyl. They look fantastic and will add such a professional touch to almost any bag! Attach them by sewing them down with a rectangle directly on the bag like on the stockholm bag, or attach them to handle connectors like on the Daytona.
I recommend going to youtube to watch this video.
It'll give you better quality then the embedded version.
I'd love your comments on this video, any and all helpful feedback is most welcome as I'm so new to video making =)
