I have made a dozen Jacob Ladder quilts over the years and always use this method to make 4 1/2 inch HST...sew 2 4 7/8 peices of fabric together, pencil down the center, sew 1/4 inch from pencil mark and cut on pencil mark...WELL, last night, I had some time and went scrolling through the Tuterial section of this board and found ''quick way to create half square triangles'' ( the name to look for under Tutitorial ) and let me tell you....this method WORKS!!!! I used one 7 inch square of dark scrap fabric and one 7 inch square of light fabric...well starched first....layed them RST, sewed 1/4 inch around the edges and then sub cut from corner to corner and Viola, I had my 4 HST for one Jacobs Ladder Block!!! These 4 PERFECT HST, can also be put togetther in a scrappy type quilt as the 4 blocks put together, will give me a 8 1/2 finshed block. There is a ''formula'' on the 3rd page of the tutitorial, on how big to cut your dark and light squares, but I find it is always better to ''practice'' on scraps before I cut into my good fabric. Off now, to start another Jacobs Ladder for Christmas....in July!!!!!
