16. Sew together each of your two chevron pieces, right side to right side on both angled sides and the short end. Turn them right side out so that you have 3 larger grey chevron pockets and 3 smaller colored (orange or blue) smaller pockets.
17. Attach the colored chevron pockets to the grey pockets. (Either by machine or by glue) On a nine symbol gate, that meant my chevrons were between every third symbol. The open tail end of the chevron should overlap onto the bottom of the bed. The longest part of the tail, tuck into the “seam” between the base-wormhole and the gate-sidewall.
18. Spot glue the base-wormhole to the gate-sidewall several times for added stability.
