48 Crown Heights North I 1894
The ribbon crossing is a simplification of the twist above, but where this one stands out is the use of five stripes for the ribbons. The tradeoff being there are no feature strips. The outer mahogany and maple stripes are 1/4". The inside walnut is 3/4". The inner section is 1-7/8" wide. Giving a pattern width of 5-3/8". This will require a new spreadsheet.

219 Crown Heights North II c1907
This was the most expensive border in the house. The house had six borders that I photographed. Skinny bands are 1/4" wide. Walnut in the ribbon middle is 3/4" wide. In between ribbon is 1-1/2". Making the pattern border 5" wide. Surrounding is 1-1/2" oak. Inner field is straight fingerblock with three 1-1/4" and six 1-3/8" slats making a 12" square. The floor had a wax finish.

18 Lefferts Manor 1909
This is the above, but with every other repeat stretched. This can go around the corner, like the above, but the lovely corner block makes it easier to lay. The pattern introduces 67.5° angles, making the dimensions much more complicated. Inner maple band is 1/4". Outer walnut bands are 1/2". Inner square is 1-3/8". Oak strips alongside pattern are 1". This is the Extended Variant on 2-Ribbons-Gaps-Overlap spreadsheet.

It looks newer than 1898. Could be a refloor. Lots of 30/120 angles. Maple strips are 1/4" and mahogany center is 1". Overall pattern width is 7-5/8". I didn't think to get the distance between rhombuses. Field is elongated fingerblock using four 2" wide slats. Probably 16" long.
