Hi @Amoni - thank you for the feedback - I think if a professional looked it this they would laugh ..we are not pros by any means - but we have landscaped a lot of yards ( our own yards .. not as a business) the work is pretty easy - it's coming up with the designs and the layout that take more thinking - the dogs love to hang out in the yard with us when we work - as far as the sand and cement - thanks for the suggestion - there is actually a sand compound called "joining sand" that helps to bind the stones together better - so far - we have done this a few times using just sand and the rocks never come loose - it seems like sand would not hold them together tightly - but it really does - the last one we did has lasted over 7 years so far and they are SOLID - we did however think about using some cement dust in the pea gravel that we laid down ( no pictures of that posted yet) to make it more solid - thanks for checking out my blog - I hope you come back to follow up with the updates.
