I need to add this one to my list. It's really cute.
The only stockings I've stitched on light weight fabric like linen are the Better Homes & Gardens Heritage Stockings which are very detailed and have fractional stitches.
Although in general I'm not an Aida stitcher, I feel that my "simpler" Santa stockings look better on a sturdier fabric. Jobelan 28 over 2 used to be my favorite fabric, but I haven't had local access to it for sever years. Since my local needlework shop closed, I've been using Aida or Salem cloth 14 for my stockings.
I think the bolder fabric suits the bolder designs very well.
