Yeah, I was considering using upholstery glue and a staple gun, however I just thought since you have to allow it time for the glue to dry you need to allow the vinyl to stay firmly in place so it doesnt look crinkled shortly after you apply the glue, which is why i thought my way of using the aluminum strip would keep the vinyl firmly in place.
Plus, if you notice in some kitchens in houses, Aluminium strips are used to keep the lino firmly placed on the floor, which is where i got the idea to use the Aluminium strips for the Parcel Tray.
Also, the aluminium strips are underneath the tray, and im planning to paint them black so they wont be so they will be hidden unless you tilt your head underneath to view it..
But by the way, thanks for the positive feedback
