Thanks to you both. Had a look on Youtube and spent many an hour looking at things I didn't even know existed!!!
Have however finally made me a smash book which I'm quite pleased with - and yes, it was definitely cheaper than Hobbycraft!!!
I wanted to make quite a big one but couldn't find anywhere that either a) stocked the 1 1/4 inch Bind it all Zutter wires or b) did stock them but didn't have them in stock
So I had to settle for one with less pages than I was hoping. I also thought A4 size would be a good idea. That is until I went to cover the covers (if you see what I mean!) As scrapbooking paper/card is 12 x 12 it wasn't big enough to cover the top and bottom of the cover. (Sides only being about 8" wide were fine.) It's now got striped covers!
So, although it's not ended up quite how I imagined it would do, I'm fairly happy with it - and have found a couple of issues that'll I'll know about for future reference. Think the biggest I'll do next time is 8 x 8.
Thanks for your help ladies, much appreciated as usual.
