GENERAL
Be careful to hold flags high (or better yet, drape them around your neck) when not spinning them so as not to step on or tear them.
Do not tie flags together; this causes tension in the weave of the silk and will shorten the life of the flags.
Do not attempt to repair flags on your own if you notice damage. Contact the flag maker. Flags can often be repaired if attended to promptly.
STORAGE
It is best to roll flags up before storing. Fold them lengthwise (toward the longer end) two or three times and then roll them.
Flags should be kept in a darkened drawer for longer storage, or in any clean, dry, dark space where the flags can breathe and are protected from light.
If flags become damp, allow them to air dry before rolling or storing them.
When transporting flags from one location to another, place them first in a plastic Ziplock bag to keep them dry. This bag can then be placed in a backpack or other bag to keep them out of the sun.
Do not store flags in a plastic bag for an extended period of time as this will cause the silk to break down.
Do not place flags against leather, wool, or other damp fabrics.
CARE
Wash your hands before flagging. Dirt and oil from your hands can damage the silk. It's also a good idea to keep your fingernails short so as not to snag the fabric.
Avoid getting sunscreen or other lotions on the flags.
Keep flags dry. Damp or wet flags can transfer dye and/or become causing discolored.
Keep flags away from direct sunlight when not in use to prevent fading.
Tiny loose threads should be cut carefully; do not pull the threads and do not cut the fabric.
WASHING
Flag makers will do everything possible to remove excess unset dye before shipping the flags. Some unset dye may still be present on your flags and could come out if washed. Routine washing is not recommended. Some unset dye may transfer or come out, however, if the flags are stored when they're damp. This dye may come out if the flags are washed properly. (The best option is to keep the silks dry and there will be little need for washing them.)
If you believe washing is necessary, hand wash each flag individually in warm water with a drop of dish washing detergent or baby shampoo. Keep the flag moving while washing. Plunge rinse the flag in a separate bucket of cold water. Gently squeeze the flag to remove excess water. Roll it up in a towel and pat dry. Iron with a setting appropriate for silk until completely dry. Repeat if necessary. A video on how to wash flags can be found HERE.
