I really mis-understood! If you have 5" squares already cut then the finished size of this square will be 4.5". So to get 4.5 ' HST the you need to take 4.5 +7/8= 5 3/8 and cut you new blocks for HST 5 3/8". or as DUNSTER said round up to 5.5" and cut to size. Draw a line on the diaginal and sew 1/4" on either side. and then cut down the middle.
