Set of 2 Antique Linen Breakfast Tea Napkins

How do you imagine using this set of 2 antique white linen breakfast / tea napkins? One napkin is slightly bigger than the other suggesting original use of one as mat on tray, & one as doily under tea cup. Use your imagination. One corner of each has the cursive letter S, original owner’s initial. Lace style netting around all edges with slightly pleated corners. Excellent condition except for 1 tiny spot on smaller napkin(last photo) Maybe be Leron Linens but no proof. Approx measurements: larger~12 1/2” per side unfolded flat, 6 1/4” per side folded. Smaller: ~ 11 1/2” per side unfolded flat, 6 1/4” per side folded.
