In pursuit with the world’s largest jigsaw puzzle

One of my ambitions is to do the worlds largest jigsaw puzzle (called LIFE) which is 24000 pieces in future.In doing so I have started the miniature version of LIFE which is 3000 pieces.Currently I have completed quarter of it which is around 700-800 pieces.Planning to complete this end of the year if time permits to do so.
Here is the full image of LIFE after you complete it.

Here is my last puzzle.

Recently I completed assembling the 1500 pieces jig saw puzzle.Before this my first puzzle was a 500 pieces one.It was a gift from my good old friend Amila Jayaratne and this one was presented by my father-in-law, Mr. Gunatilake.
This new puzzle by no means a easy walk in the park as you can see in the image above.
Normally you start the puzzle by separating the border pieces.So I too stuck to that but to no avail.The reason being there are no contrasting images to identify the correct pieces(Its just a single color boarder ss you can see in the image ).Then I was thinking how I am going to tackle this new challenge.So I changed my strategy.

Since there are clear lines , circles and letters , I started to separate them out.That was indeed the way to go.Then I first assemble the circle area.
After that it became relatively easy till I getting closer towards the border area.It was very hard to find the correct pieces and it took a considerable amount of time too.
After spending around 30 hours within the span of 2 months, finally , I managed to completed this.

My ultimate goal is to complete the world’s largest jig saw puzzle which has 24000 pieces.I have already ordered the miniature version of that which has 3000 pieces.Nishad ayya will bring that for me from UK end of this month.
Waiting for that .
