Love the kind of quivers that have the extra sleeve on the back for just one more arrow. My Selways have enough space in the hood for another arrow but no corresponding slot on the gripper. Not wanting to abandon them altogether, I came up with a super-simple way to eek out another arrow with the piggy-backers I had on hand. Effectively turns a single arrow slot into 2. This allows you to install an extra arrow on 2 separate bows since piggy-backers are sold in pairs.
