I wouldnt ask them first but I might send a note and tell them how much I loved their layout with a link to the lifted layout. I have only had a few people lift layouts from me and it was always really an honor honestly they liked something about my layout enough to lift it. I think the only time someone would be offended or upset is if you directly copied a layout or created a layout with no mention of the original layout in your credits. Scraplifting is really nothing more then using a layout as inspiration and really who could be upset that their creation inspired another person to create something? Thats one of the cool things about this hobby is the community and the sharing
