Here is another useful project made from something that would have been tossed into the trash. After my neighbor saw my Tarp made from Feed sacks she asked if I could make a Kennel Cover for her Pet Pig "Buddy". Buddy needed protection from the winter elements and wanted half the kennel covered and the sides able to roll up for ventilation, down for wind breaker.
The first part of this project is done much like my Instructables http://www.instructables.com/id/DIY-Tarp-Cover-Made-From-Feed-Sacks/
and to make it easier I will include those instructions here as well.
While working with these 2 projects more project ideas from feed sacks came to mind and look forward to posting them in the future. Here is one idea, You could apply this shelter project by substituting with Pallets as the frame and the Feed Sacks to cover it. This would make an ideal Temporary Shelter for animals or outdoor equipment with very little cost to you Hope this project has gave you an helpful idea.
