Numbered End Cards from Ashton Potter
Around September 1st, 2005, Ashton Potter started using End Cards that featured a number in the 'NOTICE' triangle.  Below are three examples with an assortment of numbers as high as 30 on the New Mexico Rio Grande Blankets end card.  More information is sought on the use of these new numbers.
