Step 2- Fold the tube in half all the way around and pin it. You should have a two layer tube with the raw edges at the top and a fold at the bottom, like this... (BTW- blogland.... meet my sewing table). Pin in place at a few places so it's easier to work with.
Step 4- Fill 'er up with flowers!! The more the better... but that's just my opinion ;) Insert flowers through the opening. Shake them around and try to distribute them a bit so you can see when there's enough.
Step 5- Close the opening.
Step 6- Make your elastic casing. If you aren't using nylon fabric or some other non-fray fabric, you'll want to fold your raw edges under (unlike the picture, where the raw edges are left poking out, but my fabric is some kind of funky polyester/nylon half breed that doesn't fray). I fold the fabric over and since I'm using a 3/8" elastic, I make about a 3/4"-1" casing, so that it's easy to pull the elastic through. I hate using pins so there are none in any of the pictures, but you may want to pin things in place if you aren't good at eyeing seam accuracy. Make sure you leave an opening to run your elastic through!!
Step 7- Pull your elastic through the casing, sew the two ends together, and close up your casing. I purchased a strap turner (notions section at Joanns) and it has been an amazing tool. I use it to pull elastic through every time. It's basically a long skinny piece of metal with a hook at the end (you can see a bit of it in the above picture, it's to the right). I just hook the elastic and run it through as far as I can without bending the metal; then I pull it out, pin the exposed end of elastic, and insert it into the other side, hook that side of the elastic, and pull it through the rest of the way. It's quicker than the safety pin method, well... to me it is.
Step 8- Shift your flowers around a bit to distribute them evenly and VOILA! You're done!
