“That none should wear on her head any lawn, cambrick, tiffany, velvet lawn, or white silk wires, either in any kerchief, koyfe, crest cloth, or shaddow, nor any linnen cloth therein, saving such linen cloth only, as should not exceed 5s. the ell, nor any lace or edging upon the same or any part thereof“… 
English ell is equal to 5⁄4 yard, or 1 ell= 1.25 yards.
£1 = 20 shillings (s)
1s = 12 pence/penny (d)
Measuring Worth , calculates a 16th century £1 = £199.10 in 2014 values. In US dollars £1 = $1.57, or $321.54 to £1 in the 16th century.  This mean a female would be restricted to linen that is under 5s per ell or modernly, $62.22 per 1.25 yards.
Linen used in this project retails for $9.75. It is a nice medium weight linen, with an even weave. It performs well in a work environment and holds up well under repeated laundering. I am using a basic woman’s coif pattern as seen in extant examples.
The edges have been left unadorned as per the requirement:
“nor any lawne, velvet, tiffany, cobweblawne, nor white silk cipres at all, other than about their neck or otherwise ; nor any linnen cloth but of the price of 5s. the ell, or lace or edging whatsoever, but plain hem and one stitch “
