How to Granny-up your old tee-shirt.
I have a problem with gaping neck-lines. (Probably from the way I nurse my babies. It's very destructive to tee-shirts.) So here's how I solved the problem. It requires: one old teeshirt; one old granny doily. (I love old granny doilies). A sewing machine helps, but hand-sewing would be almost as quick. Note: I apologize for the grainy photos.
First, lay out your doily and your shirt.
Fold the doily in half and sew along the straight edge.
Next, turn the shirt inside-out and lay the doily on the neckline, wherever you want it to go.
Pin it in place.
Turn the shirt right-side-out, to make sure the doily is where you want it.
Sew along the neckline on the outside, to secure it.
Here it is being snuggled-upon! No more gaping shirt front.
Here it is in another colour (it was only pinned at this point, so it's a bit flopsy.)
