I am a tutorial writer, you can find my tut site addy in the link below this one, and novice scrap kit maker. My Scraps are Tagger sized. My older kits are in PSD format in a layered file. PSD format works with Photoshop and PSP. I am now making my newer kits in png format which seems to work with most graphic programs so hope that eliminates any further issues.
I would be happy for you to use my kits in your tutorial creations. Of course, send them here to my blog to download the kit. If you do use my kits in your tutorials I would love if you would send me the finished tag. I will be happy to host it and a link to your tutorial on my blog. You can contact me at rockin77@gmail.com. Thanks!!
