First off, measure your tulle like I have it below. Measure out enough that you could tie a bow with a little bit of leftover.
Cut this, and cut 4-5 more strands that are the same length.
Next, take all of your pieces and bundle together, and tie the first part of your simple bow...just loop the pieces together like I have them above.
Finish tying the "shoelace bow," making sure the end pieces hanging out are about the same length as the loops.
Then, put your scissors through each loop and cut the ends.
See, told you that was easy! Once you start tying bows this way you'll never go back...it looks so pretty and is so incredibly easy.
Now get to wrapping those presents! :)
