This blanket used Scheepjes Stone & River Washed Mini packs (2 full packs and a small amount of a 3rd pack) to create a lusciously colorific blanket with 56 colors; the blanket has 2 of each color for a total of 112 squares.

The solid granny square is easy to work up and memorize, and the majority of the squares used 1 mini skein. I did find there were times when I needed just a teeny bit more yarn to finish the last 4-8 stitches however, so I purchased a 3rd mini pack. You may be able to get around this by using a smaller hook.

The join and edging used most of 3 50g skeins of Scheepjes Stone Washed.

Of course, you can work this blanket up in any yarn you like, and any weight. Adjust your hook sizes accordingly. This would be a great scrap buster project. And of course you can adjust the size by making more or less squares.
