First, you would need to determine how many inches of braid is needed for the perimeter of a blanket. 
(23 × 2) + (24 × 2) 
46 in + 48 in = 94 in

Next, you would need to do is convert inches to meters.
1 inch = 0.0254 meters
94 in × 0.0254 m = 2.3876 meters

Now, since braid can only be purchased by the full yard, you would round up. 
 2.3876 meters ≈ 3 meters

You would need 3 meters of braid.

I hope this helps!
