I have been making puzzles for 4 years now, and my favourite brand has always been Educa. There are a lot of reasons behind this. To begin with, they have a wide range of options. A person who wants to give it a try can find easy pictures with 500 pieces while experienced puzzle makers opt for 1000, 2000 and above without hesitation. That's because piece shapes are good and the puzzle holds itself perfectly.Also, Educa guarantees to send their customers every missing piece provided that the puzzle is still produced, and they really do. Buying an Educa puzzle, you can be sure that you'll be able to complete it no matter what. Every puzzle comes with a small packet of puzzle glue as an extra bonus, so you never have to search and buy puzzle glues, and you're always sure that the glue will not ruin your precious work. The only important thing to be careful is, measuring the amount of water precisely when preparing the glue. Just stick to the instructions and you will like the outcome as much as I do.
