A5 Dodopad for personal filofax!

After a brief flirtation with an A5 filofax, like many others in the last few days, I have realised the A5 size is unsuitable for me. It's heavy and bulky, and I'm already happily set up in the much smaller and more portable personal-sized filo. The more I fiddle around with the set-up of my planning filofax(es) [as opposed to my information filofaxes], the more I realise I am definitely a 1-life, 1-planner girl!!
I love my personal-sized filofax... although I haven't posted about it here because it's constantly evolving. I have a day on 2 pages Day Timer Flavia insert for the current week, which gets changed out every Sunday, so the old week gets moved out and the new one gets moved in, and I have a Day Timer week on 2 pages Flavia insert for forward planning, that stays permanently in my filofax. But I struggle to plan which university work to do when on these sheets. Last September I bought this academic year's Dodopad insert for my A5 filofax, which is brilliant, and it works for me (although I can't use Dodopad for normal planning/organisation of my time, I use it well for organising when to do which piece of homework). Because the dodopad is so good for me, I want to use it all the time, but I don't want to have to take my A5 filofax everywhere with me. I need to use it in my personal-sized filofax.
Dodopad makes a personal-sized filofax dodopad insert, but it is a scaled-down version of the larger dodopad, and so the whole page is shrunk, meaning the individual boxes are just tiny!! At this size, they would be very difficult to use.

I considered just buying this insert, but I know it would end up being too small, and I already have a dodopad in A5 size for the rest of this academic year. So I thought, would it be possible to make the A5 dodopad into a personal-sized dodopad?

I took an old page, and laid a piece of filofax paper over the grid of the A5 dodopad. It fit vertically, but horizontally it was at least 1 column too wide.

I hope you can see the personal-sized flyleaf over the grid, showing the boundaries of the page.

I was willing to lose 1 column from the grid; I work left to right, and rarely reach the 5 box of the day.

Here's the sheet I cut and the rest of the paper, showing what was cut off.

1 column at least gets chopped off

On the back, some of the lovely designs and writing that make the Dodopad so unique and cute get chopped off :(

Depending on where you cut, some of the holes go through the dates on the left of the grid.

Sorry about the shadow :(

I'm considering doing this with the rest of March's pages- I think this could be brilliant for my 1-life 1-planner!! 

What do you think? Will you do this yourself?
