This is good advise:

: Another thing that I did that helped out was to carve the cheater strip
: first, temporarily put it in place on the fixed strip, and then pull down
: the next full strip to meet the cheater strip. This was slightly easier to
: pull the next full strip to meet the cheater than carving the cheater to
: fit the gap.

However, there might be instances where it might not be practicle, say if you are going for a particular pattern and pulling that next full strip down to meet the cheater distorts your "art". I haven't had the confidence to get that fancy, so all my cheater strips were set to fill gaps where this advise was very practicle.
