first of all, amazing and soooo sweet! I loved how you stitched him, is so cute ^^
about how to delete the double pictures...very simple ;)
click on "Edit" in your post (you can find it at the very bottom, near Buzz, Google and so on icons)
once you're in editing mode just click again on the "Attach" button (the one you used to upload the pics), there go to "Attachment List" and just click on the "X" icons (at the end of the attachment, is on the very right) on the attachments you want to delete.
done this, just click on "Edit" button at the end of the post and all is done ^_________^
