I-cord loop to use for a button

I have made a sweater that calls for buttonholes but I wanted to use i-cord loops as button holders. What is the best way to attach these loops to the right front of the sweater? They are going onto a double moss stitch pattern. Thanks for any advice!

Could you make a i-cord edging like this one, loop the icord at 3-4" intervals?

Here is a pic of another i-cord edging that incorporates space for button

Here’s the button to go with it-

I’m not entirely sure this is what you want, but I have these types of “frogs” on a sweater a dear friend bought me.

I really do like the style.
