I don't know how complex your instructions are or if you're just leary of making that first cut. I'm making a wall hanging from a kit and I consider it complex and a new technique....so here's what I'd suggest (and have been doing with this current kit)
READ the instructions....look at the fabric....READ the instructions...match up the fabric to where they go per the instructions....READ the instructions....make your own notes if necessary to help you understand the instructions you read....READ the instructions....and start when you're rested.
Good luck - post the pattern name and/or picture. Perhaps someone's made it already and can help if you have more questions.
