Wow, that's a toughie. All I could find were some references to it.
* "ruled paper and graph paper came into use some 50 to 100 years ago"
http://www.pandava.com/4stripes/whatE.htm* "I also picked up a 1907 copy of 'Lessons in Garment Drafting' by Mrs. Mae
Milbourne gingles....It has 38 printed pages of instructions for drafting patterns for plain clothing from the era, and rest of it is blank ruled paper"

* "As Fitzpatrick observes, ruled paper was not available to [George] Washington, and he obtained regularly spaced lines by using a ruled guide-sheet beneath his writing paper. 'This practice gives us evidence of his failing vision, as the diaries, after the Presidency, show frequent examples of his pen running off the outer edge of the small diary page, and whole words, written on the ruled guide-sheet beneath, escaped notice of not being on the diary page itself' (John C. Fitzpatrick, ed., The Diaries of George Washington, 1748-1799 [4 vols.; Boston and New York, 1925], 1:x).
