Note: When a symbol is drawn, it is done so using the spell focus on an IG level. OOG however, other tools may be used to draw the symbol.
Sigil is a spell sphere that requires the user to cast spells on pre-existing symbols drawn upon the skin of targets that have spirits. These symbols can be temporary – quick dashes of paint before a battle – or permanent tattoos. The symbols must be created in game; a player cannot simply say the symbol exists in it. It needs to be represented. Symbols must be re-drawn for each casting, even if cloth is used. Tattoos that exist out of game on a player are acceptable as Sigil symbols so long as they fit the requirements. Sigils can be placed on skin (unless the sigil states otherwise) or on cloth attached to the body, such as an armband. You must have the target’s OOG permission for both the location and painting material that’s used on them.
Sigil symbols must remain visible at all times, both prior to the sigil being cast and after it has been cast.If a symbol is wiped off or covered for more than 1 minute, the spell effect will end. Sigils must always be drawn in blue. If a sigil is drawn on a limb which becomes severed, the sigil effect will end.
The rules say that Sigils can be placed on cloth, is this solely OOG or is this IG as well?
For example, if someone is wearing an armband with a sigil on it because its -20 OOG, IG are they wearing an armband or do they have that symbol actually on their arm?

It's OOG. The armband represents your skin.
