I bought some stencils from a board member and can make 31 triangle squares at a time or just one. THEN I also bought a JUNE TAYLOR Half Triangle Square RULER.... (it is awesome) After using stencils I square up 100% with June Taylor. Works like a champ.... Never will I be without either one of these items again... So awesome.... If you want name of stencils let me know I will go look. NO WASTE.... NONE :)
