Knitting Advice – A lady asked advice on blocking

A member of a knitting group on Facebook asked if it was all right to block your wool project with a hairdryer (hot). The answers she got varied, but I think blocking with a hairdryer would cause it to block in a buckled or rumpled way. There is really no easy-go method for blocking other than using a blocking board or squares and many blocking pins placed evenly. It is worth it if you have made a nice piece to take that time. Any other ideas for this nice lady?
