Note: Cannoli are made with chocolate. Actually you could use the forms for any cookie that you might want to have a filling. Simple sugar cookies could be baked with these forms tor making unusual shapes. One of my first forms came apart before I modified the design. Otherwise they worked great.
Step 1: What You Need.
Two cookie sheets (a dollar at the Dollar store).
Knife or old scissors.
Ruler or other straight edge and measuring tape.
Broom, pipe, or pvc tube (under 1" diameter) for the form.
Step 2: Prepare Cut Forms.
Fold bottom of cookie pan in half.
Unfold the bottom.
Cut along crease ending up with two long sections.
To make each form: (repeat as needed).
Take one section and measure up 3 3/4 inches. (hint: you might start at four inches till you get used to making a finer crease.
Crease with and object that has a dull pointed end. (i.e. screwdriver,)
Cut along crease.
Step 3: Bending the Form.
Take that fold and part way bend it back on it self to make a groove for holding the other edge of the foil.
Insert other edge of foil into the groove you just made.
Press down and seal end along the line to make a tube.
If you used a pipe as a form you can roll the pipe over the crease to further seal it.
Done! Time to make cannoli!
Step 4: Our Cannoli.

They do not have to be perfect. The wonderful taste will override the odd shapes. Besides, they are rustic and home made.
Note: at the time of this picture I had a few more to complete with the cheese filling and dunking in the ground peanuts (unsalted).
