On the wall hangings I did , I rocked . On curves and corners I stabbed . On using pvc hand hoops , just make sure your top is very loose , looks weird but this is the way it needs to be . If you can find the Simply Quilts video with Luixin Newman [ the thimble lady ], please watch . She shows how loose your top needs to be . I think I spelled her first name right [ ? ] She may have a website , I'm not sure . She sells her thimbles . Annie
