Or can I knit with pencils?
From the Municipal Court of Seattle Office of the Jury Commissioner:
Waiting is an unavoidable part of jury service. [...]There is an extensive and current magazine collection but we do encourage you to bring reading materials, crafts and other projects to pass the time.
Everyone entering the Seattle Justice Center, except law enforcement personnel, is required to pass through a security checkpoint. [...] You are also cautioned to leave at home items such as scissors, knitting needles or pointed objects over 2" long which are routinely prohibited from the building.
