I think you meant to post this on @Colleen Jorgensen 's pillow post. If you click on her name it will take you there :)
Hi Gale! I didn't make it weather resistant as we're still in the 90's here in Northern California. But what I've done before is take an old vinyl tablecloth, wrap the pillow and then put burlap or canvas dropcloth over it. Our porch is covered, so unless it's a windy rain, it won't receive dampness until the temps drop. Thanks for asking!
