But Fowler called upon her patented preservation techniques to save it from further deterioration. She used dyed-to-match silk thread and employed ten assistants to reinforce the 1020 sqft relic. They anchored it onto Irish linen with 1.7 million of Fowler's special honeycomb patterned, six-sided stitches. It took eight weeks to finish the preservation process. Upon completion, she claimed the restored flag would "defy the test of time," and charged the government $1,243.
