Scrapbook Layout

I had been 'sitting on' a 6x6 album for a number of months, and felt it was time that I filled it up. I wanted to use the same colour theme right throughout the album, so I shoose a Simply Scrappin' kit from Stampin' Up! to create it.
When designing a page layout I have three main steps that I know I need to do in order to acheive a successful page layout.
Choose your photo/s first, then add your colour scheme and any embellishments to 'dress' up the layout. Add your journal details. Finished.
Well that sounds good in theory - but I am finding that what would normally be a 1 hour project is easily turning into a 4 hour project. And often that is without interruptions! Am I getting too fussy?
