I thought about this too, and I know a couple of plan to add more 12x12 items. I need them for myself! Ack!
I would love more 12x12 DYD templates / papers! I saw Allison's paper pack this year is 12x12 but comes with an action to crop to 6x8. I thought that was a pretty creative way to offer both sizes.
Those are awesome! I need to figure out how to make actions again. This is not something I do regularly enough to finesse them. hahaha!
I love mixing up sizes of pages in my PL- I am doing 9x12 this year- but have all sorts of page protectors in there (love that fuse tool!) and like Maribel- I have a few extra Cmas only mini books i make - some are detailed like December daily- and some are more photo focused- the kids love that these all come during the holidays in a big basket- You could get your 12x12 to have a smaller feel by leaving a few pockets blank surrounding your 6x8 pages- so its not such a stark contrast- either way- we are the picky ones! The family would love it if the photos were in a brown paper bag! !
Last year I've done my first Daily December and I've i corporared it in my PL. So for december, instead my usual PL pages, I've my DD. I worked in 12 x 12. This year, I will re do the same size. But next year, I would like to change the format. i would work with 9 x 12. So my question is : is there some pocket template here with the size ? This year I use this template by Lynne-Marie https://the-lilypad.com/store/Pocket-Scrapping-Template-Builder.html
I don't think there are any 9x12 templates, but you should be able to resize 6x8 templates. They are the same ratios.
This is basically what I'm doing. I made templates for myself using Ali Edwards "blueprint" for how she set up her DD album this year. Each 12x12 page has a 2-page 6x8 spread in the middle, but shrunk down about 75%. I made 25 templates, but I doubt I'll use them all. I'm going to use them as a starting point, and if I want to make something different that day it's ok.
