In past years Target sold outdoor chair cushions that had one rounded edge like the attached image. I have a few old ones that are kind of mashed, so it's hard to provide exact dimensions. My local Target doesn't have them this year. I need a black cushion. It won't be used for seating. A gizmo I built requires a rugged, outdoor cushion. The Target cushions were about 3 to 4 inches thick. They were stuffed with a firm polyester batting. (Very cheap cushions use the lowest grade foam rubber.) If I remember correctly, the Target price was $18.00. They lasted a couple of years, which was ok for an $18.00 cushion. Rough dimensions for the Target cushions were: 18" - wide 16½" - deep 3 to 4" - height A slightly larger cushion is fine. It must be a smooth fabric. Not the kind with pleated buttons. I can search eBay or Amazon all day, but I have no expertise in this area. Can someone help me find the cushion I need?

My property sits on the downhill of the block. My garden is in the corner of the lot and when it rains water from the lots next to me flows into the garden and eventually floods it or makes is so wet I can't work in it. I was wondering about installing a drain around the perimeter of the garden to avert some of the water. I was thinking about a 4" perforated corrugated drain pipe. I need about 100' to do the "top" and both sides. Coming from my house is a 4" tile that connects the downspouts and leads to a pop up emitter. My idea is to splice into the 4" pipe and connect the corrugated pipe. Is this a good idea or not? Do I use the pipe with a sock or just go with the pipe without the sock? How deep do I dig the trench?
