You also take away the risk of dropping pins or even worse - disappearing pins. Nothing's worse than tip toeing across the room dodging pins and needles.
Basting Spray is only temporary. It comes out in the washing machine or breaks down over time. And if your worried about gunky over spray; this adhesive comes up in seconds with rubbing alcohol.
