When I do create a double LO, albeit ever so rarely, I usually tape the two background sheets together on the reverse and approach the LO as a larger, different shaped single. Therein might lie the problem? Perhaps I don't like the rectangle shape? I know I'm not a huge fan of 8.5x11" LOs. I mean I love what other people do with that format, I just struggle with it myself. Another thing with double LOs is that they usually mean multiple photos and I'm not huge on using more than one, perhaps two, tops, three, photos.
Here are just a few of the doubles I have done which, as mentioned above, I feel 'comfortable' (LOL!!) sharing ..
17 Years and 11 Days
A love ever-lasting
Enjoying challenges like I do, perhaps I should challenge myself to create more double LOs in 2013? I know for sure that if I scrapped more of the photos from my old photo albums I would definitely have plenty of 'multiple photos fodder' to work with! Emptying those albums is definitely a goal for me and one I confess I haven't worked particularly diligently on. Also one of the Scrapbooking Memories Masters challenges for 2012 was to create a double LO and the LOs the 2013 Masters and Honourable Mentions came up with were fabulous! A couple of them have actually stuck in my memory and very little sticks in my memory LOL! Perhaps I can feel some scrap lifting coming on? :)
PS: Do you notice any similarities between 17 Years and 11 Days and A love ever-lasting? LOL I subconsciously scrap lifted myself!!! :P
