I forget which YouTube/blog I was looking at, it was probably the Sly Flourish one, but still I came across a link to this great website called Hexagonal Graph Paper PDF Generator.
Which was just what I was looking for.
As the screen grab below shows it allows you to generate a custom sheet of hexagonal graph paper to your specific needs. Mine was 1/2 inch hexagons on a landscape A3 page. Which you download as a pdf.
There are some pregenerated pages as well for visitors to download if they match what they are looking for.
I took the pdf the site generated and took it into GoodNotes, and then saved the page as an image so I could use it in Pixelmator.
In Pixelmator I created a new image using the one just saved. That way I knew it was an A3 sized image. Then in another layer I brought in the map of the Sword Coast. Which I resized so that each hexagon on the map represented 25 miles. Using the map scale was handy for this.
Below is a screen shot of part of the finished product.
The final image is A3 size and is something I can print off and use with the players for when they hit the high seas.
If you remember back in the post where I briefly summarised different options for making travel interesting I mentioned the D&D adventure The Tomb of Annihilation and the method they used within the campaign. This map would be ideal for that method. But it might have to be tweaked to take into account the greater distances travelled by ships. For instance a Keelboat can travel 75 miles or three hexagons in a day.
Sadly for the players we will probably have to play test one or two of the ideas I have as solutions.
We now have a date for the fourth session. Which is the last Saturday of the month, which also happens to be the very last day of the month as well.
