This is the McGyver solution to a lot of stuff, a must have to build your own light modifiers and to use Gels easily
Without Velcro we would not have all those beautiful solutions, for example;
This light modifier kit uses a lot of velcro, it does not damage your flashes. Source: thomas-schwenger.de (English article)
Also go to http://www.diyphotography.net/ and search for Velcro and you will find a lot of projects.
I specially like this solution for gels;
Attaching Gels to your Flash;
(Note: I would use rubber-bands cut from a bicycle inner-tube around the flash and then use non stick Velcro around it. The rubber band prevents slipping off of the velcro strap)

Instead of using a rubber band you could use gaffer-tape wrapped around the flash. See article here: http://flashzebra.com/tips/attaching_the_gels/index.shtml
Gaffer tape comes in different widths and for different prices. This tape is the safest to use as it will not leave anything sticky behind after yo used it. Use it for;
- Taping gels to flashes
- Repairing a umbrella
- Taping cables on the floor or a wall
- Taping a flash to anything
- Fixing various equipment
- Hanging props from anyting
- Whatever you can think of it will stick
A website I found that sells gaffer tape for a reasonable prices. (I did not order there so can not say anything about their service.)
Despite the claims they make about gaffer tape it will not stick very well in the cold and if you leave it on to long it will leave residue behind.
