humm... well you know they probably do contract sewing since most companies don't want to higher part or full time workers since they require benefits and/or more paperwork or something cheap factories...
my mom used to sew pillows for IKEA on the side and tote bags for various companies like Henrys... her friend did clothes for Forever 21 etc (she gave me an extra jacket once )... so yupp I think that's fairly logical and usually they're scraps or somethings wrong w/ them so they're able to just brush it off so they're not stealing... she used to get some fabric from the pillow sewing company since they finished w/ that type and had leftovers... she'd use it for curtains and such
