The MRCE is a fun project to work on. I really have no skills whatsoever when it comes to all this, so I'm really pushing myself and I'm pretty happy with my results. Take it slow, read, read, read, read, measure, measure, measure, cut.
Most of what you are looking for can be found here over in the For Sale section. A few of the over items will be at a local hardware store, fabric store, or sporting good store. I know I spent a lot of time at Jo-Ann Fabrics, Wal-Mart and Lowes. If you can't find it in a store, you can probably find a How-To on making or someone is selling one on here.
