I am preparing for when I receive my A5 Holborn Zip by getting the journaling pages ready to go. I purchased this gorgeous journal here. (Thanks to Gail for posting that great idea.) I also picked up this paper punch here, it's for personal diaries.
Originally, I was using my Crop-A-Dile to punch holes in papers that I wanted to add to my Filofaxes. It worked really well, but it was tedious, one hole at a time.
This Rapesco punch works really well. I was able to punch about 10 papers at a time. The only thing was that I had to punch one side for the A5 and then flip the papers over to punch the other side. I used a post it note as a guide to line up the edge of the papers.
First, I ran an exacto knife along the edges of the journal to remove the paper. These journals have really sturdy bindings. I posted pics below so that you could see my progress as I prepared the paper, and also to get a good look at the punch.
