I want to make a simple walkway from my backyard to the front yard.

ok...really ..for the walkway to b installed correctly,you have to level .apply paving sand ,and or crushed stone ,allign,and fill the balance in with sand

If you want to do it right and save time in the long run, you might as well do the tedious stuff no one wants to do. I am not sure if your doing stepping stones or a continuous path, so I found a couple websites one for each kind. The stepping stones website is as follows: https://www.bunnings.com.au/diy-advice/outdoor/paths-and-landscaping/how-to-lay-stepping-stones

and the continuous path is as follows:

Good luck!

You will still need to level each paver or its gonna be like a fun house walk

Here's a simple one-https://www.hometalk.com/diy/outdoor/walkways-paths/garden-path-from-old-bed-frame-or-pallets-32231090?r=1

Agree with everyone who said do it right the first time. The ground must first be prepared properly so that it can support the weight of the path, and people walking on it, without the top blocks shifting, sinking, or cracking.
