Materials
      • An empty roll of duck tape*
      • Colored duck tape in your choice of colors
      • A CD ( make sure it is one you don't mind being possibly marked up or nicked)
      • A Sharpie or marker ( if you are using black as your base color, silver sharpie is best)
      • Ex-acto knife
      • Scissors
      • Cutting board or a flat surface you feel comfortable cutting into
      • Hot glue gun or super glue[for attaching accessories and clip]
      • Alligator clip ( if you wish not to clip it in your hair, bobby pins work fine for attaching to the head.)

*Something I found of ease use for the roll is keeping the last layer of the duck tape on the cardboard roll. You can use the color which is kept on as your base color for your hat. This way you are not spending extra time having to cover the roll with a new strip and making sure it goes exactly perfect onto the cardboard and that it is the right length.

Instructions

    These instructions will be for the basic mini top hat, no accessories, although I will add instructions on how I did mine. I'm assuming that you will be using the method I suggested for the duck tape roll, and I'm also assuming that you have one base color.
My point is to make this project as simple as possible when making the hat, now decorating it is your choice on the level of complexity.
   
     1. Make duck tape fabric which is larger than the CD, I would leave room for error, so about an inch or two larger will be just enough. (If you do not know how to make duck tape fabric please refer to [link] )

     2. Take the CD and place it in the center of your fabric and outline the CD with your marker upon the duck tape.

     3. Cut out the circle with your preference of cutting, I find circles are easier cut with scissors when you are looking for a clean line with this material. Although the Ex-acto knife will work just fine as well.

     4. Now take the empty roll and place it in the center of your cut out circle, you should see this will create the brim of your hat.  To attach it to the roll, simply rip out a few moderately short pieces of duck tape ( 2-3 you can decide on how stable/strong it  needs to be, so you can add more) which will go on the inside of the roll. Place half of the strip on the circle and then the other half upon the cardboard of the roll.  Add them in the points needed to keep it's hold and you're already almost done with the basic hat!

     5. To cover the top of the hat, rip out two strips of duck tape which are longer than the diameter of the roll (Once again leave room for error). Place on a strip, sticky side down, to cover only half the top so that we have over hang.  Press down along the edges of the roll where the tape has covered it to keep it sticking on. Now do the same with the second piece of tape on the other half, yet make sure that the two pieces are overlapping in the middle.

     6. Now comes the slightly difficult part, you will need to turn your hat upside down so you can cut off the overhang as close to the outside edge of the roll as you can with the ex-acto knife. The difficult part is you will most likely need to lift the brim we just attached to see where you are cutting. So cut off the duck tape which is over hanging from the roll and you have finished the top. Now be careful when handling the top, it will still and always be slightly delicate, so don't go poking the top or it will collapse into the roll.

     7. You now have successfully created the base of your mini-top hat! Now go wild with your imagination and decorate it to your hearts desire!

For Accessories

         The band around the hat: To create this I cut out about a ¾ inch wide strip from duck tape fabric which was longer than the circumference of the roll. The end of each strip had a sticky side exposed which can easily be obtained by ripping a small piece which can be stuck on each end with overhang, and the overhang will be attached to the hat itself.  So from there simply place it upon the hat. Any overlap you have from the strip maybe being a bit to long is fine, keep it, just make sure to have the strip pulled as tight as possible around the roll. Where the overlap happened I just ended up 'conveniently' covering it up by placing the duck tape rose right over that spot.   

Glue gun vs Super glue: Your choice! When you use the glue gun to attach the accessories, please keep in mind that some duck tape will melt due to the heat, so do not over-expose the tape to the heat. ( I like it some when it melts because I think it helps create a strong bond onto the duck tape.)
For the experimenting type, I would love to see how strong the hold is on the accessories if super glue is used, I have yet to try it. I know that hot glue will not keep a long hold on duck tape if the item is handled a lot, such as a wallet. Although I can tell you all the hats I have, have yet to have an accessory fall off which was attached by hot glue.

Alligator clips:  I found that alligator clips have a much stronger hold for extended wear compared to combs, so simply glue it to the bottom of the hat at the appropriate angle you wish for it to sit how you want on your head. Depending on your hair, you may want to have two clips upon it for an even more secure hold onto your head. Here I would advise a hot glue gun because you will want as much glue as possible; I think the super glue would be too thin to get the job done.
