I did the Links pattern by Lockwood.

I thought the pattern was easy to follow and the quilt was not too difficult for me as a confident beginner.
As far as I remember, I ironed the seams in each row so that they would interlock. (I did this quilt 2 years ago).
I do think choosing your fabrics is one of the most difficult parts of a bargello. I bought this quilt as a kit, since I was not confident enough to pick my own fabrics, and I loved the colors in the kit.
Give it a try, bargello's are fun to make.
