OK, going to give this a shot!
This is the first and most difficult part.
All of this needs to be on transparent BG. I have added the white BG layer for visibility.
First you must create your pattern.
I used guides and the Pen Tool set to "Shape".

Using the tools option bar of the Pen Tool, I then added a 24 pixel outside stroke which is 0.25 inches. CONVERTER

I then made a duplicate of this layer and rasterized it.
I used the Magic Wand Tool to make a selection of the outside of this shape.
Make sure the marching ant selection is only around the shape! If not hit Cmd/Cntrl + I.

Create a new layer.
Turn all other layers off.
Select your Rectangular Marquis Tool.
Select/highlight the new layer with the active selection...

Then right click within the selection and choose "Make Work Path".

You will now have a work path that looks like this.

Now we need to convert the work path to a shape layer.
Go to LAYER > NEW FILL LAYER > SOLID COLOR Hit OK and choose a color.

You should now have three (3) layers.....
The Original Pattern Shape layer.
The Original Pattern Shape copy layer.....which is no longer a shape layer because we rastorized it!
And the Color Fill (shape) layer which is 24 pixels larger than the Original Pattern Shape.
