Keeping a style sheet as you write will save headaches for everybody later on.
Writing is often an impulsive task, and momentum should not be sacrificed to detail if the result is inspirational derailment. At some point, however, you will reread what you’ve written. You will revise. The moment is yours to choose, but you will make choices about this and that. Record those decisions.
A sharp editor will compile a style sheet if you don’t provide one. It will list names of people and places, dates and chronologies, brands of significant objects, preferred spellings, the special treatment of anything.
Here is an example:
My Style Sheet
If you look carefully, you will see that certain details raise questions. Sid’s last name doesn’t match the rest of his family. Probably the writer changed the family name but missed Sid because he is only mentioned once. Karrie was 8 when she gave birth to Sid and 13 when she had Henry. This is because in the first draft Karrie was 48, like her husband, but in the second draft the author decided that she needed to be younger, which means Henry should have been made younger too, but the revision slipped between the cracks. The problem is compounded because Sid was moved from younger son to older son to explain the father-son issues between Henry and Carl.
All sorts of details become easier to keep track off with a style sheet. Henry’s Tacoma is frequently mentioned—a kind of defining trait. This is an indication to the editor that the Tacoma deserves heightened attention—its color, model year, dings and scratches, or anything that might come up later. For example, if the dent on the rear quarter was caused by a collision on the driver’s side, it doesn’t make sense for it to be on the left side. If Trixie is only 4 months pregnant, she should not be stumbling off curbs yet; if we meet her 8 months later and she is about to give birth, there is clearly a problem with the chronology. If the writer had to look up the spelling/styling of a brand name, chances are the editor will have to look it up too. If you have to look it up twice, you have your style sheet to refer to.
Story development means errors are almost inevitable. Maintaining a style sheet will help you keep track of all the changes you make. And your editor will love you if you provide a copy of your style sheet with the manuscript. It will save the editor time (and you money).
