Different size yields!?

I am currently working on a large blanket in which I took a 16 bit picture and am making a ton of granny squares and then sewing them together to make the picture.
I went and bought a whole bunch of yarn in all the colors I wanted, and some of the colors are different finishes. For example, one of the colors is a shiny blue, Red Heart Soft, while others are just flat colors.

After working on a few colors, I noticed that some of the granny squares I've made are different sizes although I am using the same tension, hook size and ply. I already researched blocking, and to an extent, that will work in making them uniform, but the thinner yarns, like the soft ones, will end up being thinner with blocking, which will make those sections of the blanket thinner and more holey than the rest. Which I really want to avoid.

What I want to know, is if there is a way to work the thinner yarn so that it will be similar in thickness to the regular yarn. For example, a finished granny square of red heart soft yarn is smaller and thinner than a finished square of red heart super saver yarn.

This is the pattern I am using for my squares

yes what you are experiencing is normal. not all worsteds are created equal. I would go back to a big box store (michaels, joanns, hobby lobby, ac moore, etc) for yarn and match the colors to the majority of the weight you have. don't use the soft yarns. they are finer and if you double them, it will come up as a bump. use store brands to try to match colors in addition to other national brands. shop online if needed.

if you really have your heart set on using the colors you have that are thinner, you can try unplying half a skein and adding that to an off the skein strand. un plying can be a major pain in the butt. it will tangle and twist on itself. unplying means to divide the 4 strands and hold 2 in each hand and pull them apart. the ball will twist your yarn in your hands will twist. let one strand at a time go to get the twist straightened out. You will have to pet it out and coax it out and untangle. the resulting 2 ply won't be the same strength as the standard 4 ply.

I would not do this. ( used to do this as a kid when I needed something else to work with) it is frustrating and you will see the 2 ply held against the 4 ply and it might not be a look you want. try it if you want. only you can know what you do or don't like.
