After the dress...

Well, if you think the fabric will make the perfect jacket, maybe this table will help. Just like with my previous skirt and pants tables, I collected jacket patterns and entered the required fabric amounts into a spreadsheet, broken down by fabric width and jacket size, and calculated the following table of minimun, maximum and average fabric requirements.

Approximately 140 patterns went into the values for 45 inch width fabric, and about 160 patterns went into the 60 inch width numbers. I included patterns from Simplicity, McCalls, Butterick, Vogue, Burda, Neue Mode, New Look, some BWOF magazines (3 issues from 2009), Brown Paper Bag Patterns & Hot Patterns. (If a pattern was labeled "Vest" or "Coat" I did NOT include it.)

To help make these columns more concrete, here are some images representing the patterns requesting the minimum, maximum and average amounts of fabric:

The pattern in my table requiring the minimum amount of fabric is this Butterick pattern, view E- the (blue) version in the lower right-hand corner. (Personally, I wouldn't exactly call it a jacket, but hey, what did you expect for half a yard?)

The pattern requiring the maximum amount of fabric is this New Look pattern, the long sleeved, full length jacket.

And here are a few more examples of patterns that called for the average amount of fabric:

Similarly, all four versions of this Simplicity jacket can be made with the average amount of fabric listed in the table:

I was a bit surprised to find that this Simplicity loose jacket could also be made with the average amount of fabric:

All three views of this fitted Neue Mode jacket pattern are also "average":

Finally, this retro pattern (the long sleeved version) can be made with the average amount of fabric:

Of course, even with a table like this, you still need to have a rough idea of the type of jacket you might make, and you still need to estimate the amount of fabric to buy. I like the table because I feel like using it helps me start my estimating from a solid foundation.

Remember that an "average" is a number that approximates the middle value - that means that there are a lot of patterns just above it, as well as a lot of patterns just under it. So if you think you are going to make an average jacket, you should buy a little bit more than the average number listed in the table above.

How much should you add? It doesn't have to be a lot for jackets.

• If you add 1/4 yard (.25 meters) to the average value for your size, you'll have enough fabric to make (on average) 74% of the patterns that went into this table.
• If you add 3/8 yard (.35 meters) to the average value for your size, you'll have enough fabric to make (on average) 81% of the patterns that went into this table.
• If you add 1/2 yard (.45 meters) to the average value for your size, you'll have enough fabric to make (on average) 87% of the patterns that went into this table.

I hope you think these tables are interesting and could be useful. I'm working on them for dresses and tops. If you have any suggestions or advice, please let me know! :)
