DIY cobblestone path for only $78! here’s the cost breakdown as well as the amount of materials i used total! 80 lb quickcrete mix: $5.91 (10) 60 lb mortar mix: $8.99 (2) sand (we used excess from our kids sandbox, but you can find some for like $5 at home depot) total: $78 (after rounding up) this DIY cobblestone path was tedious, but worth it! we used rocks that were already in our yard from when we first landscaped a few years ago. we used about 200 square feet of rock for this path and it doesn't even look like we made a dent in where these rocks used to be! also please wear gloves when handling concrete so you don't get chemical burns!! take it from someone who learned the hard way 😅
