(1) Materials: one yard each of two cotton prints (I used about 1/4 of each); one yard of heavy interfacing (Craft Fuse, found at Walmart); matching thread.
Other things I needed: sewing maching, scissors, measuring tape, iron.
(2) I put out all the stuff I wanted in my organizer (calendar, wallet, phone, etc) and lined it up with about 1/2 inch between. My fabric was about 6-8 inches longer than I needed, which I thought was a good thing. (Longer = more pockets). I cut my fabric and interfacing - two lenths of fabric and two of interfacing. (Mine is approx. 11" by 36")
(3) Iron on the interfacing following directions that came with it. (Thank heaven for those!)
(4) Sew long sides and one short side together, right sides together. Then I trimmed off the excess fabric so that there were 1/2" edge, and trimmed the corners a bit more.
(5) Turn inside out. This process took me longer than I expected and I started to panic a bit, but it turned out all right in the end. I used a capped ball-point pen to push out the corners, then ironed and ironed it.
(6) Turn un-sewn end in and sew seam. I liked the look of the stitches on the outside, so I did the other side, too.
(7) Lay out your stuff and start marking off the pockets. I did mine one at a time, starting with a medium sized item to see if I got the size right. I ended up needing at least 1/2" on each side of the item for it to fit in properly. Mark and sew until you are done! (8) Admire your work. Ask people to look at it and say nice things like "You're so clever!" or "That is great!" Feel happy. Go to your room, take out some bags, and try it out. This is one of the purses I use - it's so organized now.
Love it. Next on my list: checkbook cover to match.
