You can make this battenburg cake pouf with or without a lining. I have designed it so that you undo the zip on the outer bag, then unpick a small seam and empty some beans out before removing the bag. This is done so you don’t have to have too large a zip in place – of course you can add a zip large enough to remove the bag intact but it will be unsightly. You can also choose not to have the liner of course and just put the beans right into the outer cover, but this might cause an issue when laundering. You could also put a zip in the liner, but it is just as easy to unpick a few stitches and sew them back up as required.
