I just received my crate from last year's hunt in SA. I had some skins done, felt backing and sewn leather edges. Kudu, wildebeest , gemsbuck and others. They are folded now the way they were shipped. We are building a new home and I need to store these skins for 4 months or more. Should I remove them and roll them or just leave them folded? Let me know what you think. Thanks.
