These are so convenient.....perfect when you wish to make a gift quickly.
These are a nice weight, but after I bought them, I realised that the way I end up making my mini albums, these aren't really necessary. I never work with a white background, so I've ended up covering them with other paper, or just using them as cardstock for other projects. I just make my pages out of the colored cardstock or patterned paper, adhering two pieces together back to back. But if you do work with a white background, these are good quality.
I recommend to use these as the base for your inner pages. This ensures the pages are exactly the right size and also provides a nice, firm base (so the pages aren't too "floppy").
