This first tag is from a tut by Abstract Creations. It's written for Photoshop but I made it in PSP since I have very little PS knowledge and parts of it were just too confusing. You can find the tut here.
This next tag is from a tut by Dee-Gee Creations. It uses a PTU kit but the kit is inexpensive. You can find the tut here.
This last tag is from a tut by Just Fi. This one also uses a PTU kit but it was inexpensive also if I remember correctly. You can find the tut here.
