Puzzle Strategy

I have recently acquired 2 new jigsaw puzzles and enjoyed the challenge again
The latest one I got for Christmas and looks frightening !
As I started I thought maybe we all have different methods of Attack (not like some Autism people who can do it upside down!!)

I always start by sorting and assembling the edges and with some guidelines  of similar country etc and some knowledge of geography. It went along well.

Struggled with the edges until I put it on a cloth and measured the length and realised its not square and I was thinking it was wider than it is. So pieces I had 5cms apart actually fit together !!

I then started on the sign in the middle as the colour was clear. I was lining up the A with the U underneath, so a grid of sorts. Kept working at one piece until I realised there was another E involved!

This became a good frame for the other edges bits.

Then I started on the south america as it was at the edges and the colours (thankfully) were distinct, again geography skills helped. It might be yellow (different shade)  but Dallas was not in South America All those little lines of rivers were a put off!! 

Then it was North America and Canada's turn.

 A different shade of yellow and then pink. A bit more of a geographic challenge but not too bad.

It comes with a paper copy of the map so this was in constant reference.

I was searching for ages for something with 'or Reef"  and Gt Btn written underneath 

Turned out to be the middle of Cocos or Keeling Isl; Not Ree but Kee

One stubborn little piece was left but did not fit the space left. Then saw a similar piece, pink with grey lakes, and voila! Swapped them over !

Seas here are greeny grey

Then the challenge of Latitude and Longitude.

The map is centred on the North Pole so the equator is not in the middle and Europe runs from Italy down to Sweden so orientation was a bit confusing!

This colour is the Southern seas 

PROGRESS

 So then started sorting!

• pieces with a red line ,Tracking Longitude was not really sequential!
• pieces with the Tropic dotted lines 
• then the shades of green for the seas

These look a bit similar but are different and can be differentiated if I compare areas.

Then pieces with any writing on them 

Then I'm left with just pieces with a line through them and plain!

And the rest!

Will attack the last of it when feeling positive!
