^This. Use the water proofer that they spray tents with. I works very well and can waterproof even regular (not waterproof) blankets. Plus, it is still breathable. We spray ours every year. You have to spray them and let them sit for a day or two in a very well ventilated area. Make sure you spray the seams really well. I have never had one leak.


yup - this what I did after washing my blanket this summer. You have to use a full can on one blanket, but it works!
