Looking for suggestions. I just rebuilt my bunk and there was a strip of epdm that went over the hinge from the wood platform to the actual bunk, but that's like 3" above the hinge. Seems like if I use this in the winter it's going to let a bunch of cold air in and bugs any other time of the year. Is there any I can put directly over it? I also I noticed the bottom corners of the canvas were somewhat open to open air is there anything that can placed in those corners as well? I have attached pictures.
