I was scared to start, don't know why, cos it just like card-making - but you get to keep your work! Like that bit!!
I think a lot of people can be overwhelmed with all the hammers, eyelets etc, cos they can be quite costly - better to use brads and peel-offs. then build up to the 'hammerin' when you get more into it!
For my first attempt, I tore a load of paper into strips, then some into squarish shapes etc, threw them onto the page, and started to tidy it up and voila!! A strange mess greeted me, but I just played around with it!
