So couple of points of confusion I’m seeing in this picture and comments below,
-
a wall stud (2x4) is 1-1/2 inch wide, most builders use the cheaper sheetrock which is 3/8inch. A post-it is about 3 inches meaning those first marks/holes are at about 2 inches which is just barely past the window stud (1-7/8inch). Looks like you successfully found the next stud though. Fyi, those drywall fasteners that expand are more than enough to hold a curtain/rod and would probably fit into those previous holes if you want to move everything.
-
A curtain being aesthetically pleasing is it’s 2nd job. Historically, it’s primary reason for existence is temperature regulation. A curtain should tuck against the wall on the sides and reach all the way to the floor to stop cold air from escaping. You can have the best of both worlds with a cheaper “to the wall” rod underneath your decorative setup (like 3$).
-
You should be technically measuring, then purchasing the curtain for it’s intended length dependent on the style you want (from floor to ceiling is considered more “grand”). It’s not mandatory though as you can adjust the rod height and also the curtain length with simple hemming like with “iron-on stitching”.









I played with those as a kid for far too many years without knowing what they were actually for lol.
