Substitution question

I am looking at a pattern for a jacket that calls for Fiesta Insignia La Boheme and I was wondering if there is anything else I could use. The La Boheme is $29.00 a skein.

As long as the yarn is the same weight, you get the required gauge, and it is generally the same type of yarn, than you should be fine. If you are knitting cables or other textured stitches, than you should make sure the substitute yarn has good stitch definition.
