I am in the process of resizing an ex-hire kilt for my son as he lost quite a bit of weight.

While doing this, I removed the lining, and the interfacing in it. I have installed a linen stabilizer strap (full length of the kilt) and the canvas is also full length of the kilt.
When aligning the top band, is it aligned with the tartan in the front apron, and the back falls where it may for alignment? Or should I cut the top band and align it on both the front and the back and splice it? It was not aligned at all when he purchased the kilt.

Thanks for your help!
