The maps I drew, depicting locations mentioned in Arthur Ransome’s book ‘Swallows and Amazons’ and the 1974 film, are now available on a number of products. I though they might make good gifts.
They have large scarves, which always make a good present and sweatshirts for anyone prone to getting lost.
You’ll see cards, notebooks and prints available if you click around the site.
They have travel mugs,
Forgive me, different maps seem to fit the dimensions of each item in different ways but they offer good quality ceramic mugs .
Click around and you will find these three different designs available on the site labelled: ‘Map of Windemere’, ‘Map of DerwentWater’ and Map of Coniston Water’
They offer the same design on a tall mug here
All the items with a decorative map of Windermere can be found on Redbubble here
The map of Derwentwater is probably a better shape for an iphone cover.
Items with a map of Derwentwater can be found here
This small tote bag measures 33cm x 33cm
Click here for details of the 40cm x 40cm cushion + cover
Items with the map of Coniston Water can be found on Redbubble here.
They have the phone covers, travel mug and a selection of prints
They offer three different styles of T-shirts with this map, so you won’t get lost.
The company offer secure payments, worldwide shipping and free returns but I fear they are quite expensive. Click here for this drawstring bag
My other designs have worked better than maps. You can see some of them here.

These items are great! I already have the trio of beautiful ceramic mugs; I must get some of the other things available. The travel mug would be useful on my trips to the Lakes and I like the idea of the throw-pillow. And, as you suggest, they make excellent gifts.
