I will make a skirt for the Nordisk Alfheim 12.6. This is a made-to-order item, and it will take approximately 1-2 months to deliver after you contact me. (If the zipper color is white, black, or olive drab, delivery is possible within 1 month.) I try to select fabric colors that are as close as possible to the tent fabric, but there may be slight color differences depending on the type of tent. Please understand this. Width: Approximately 30cm, Length: 6m x 2 pieces (12m) *I have seen this product being sold on other sites using the same photos and text. I only list on Mercari, minne, and Creema, so please purchase from other sites at your own risk.
