Hi! I am new to crocheting and had a question about yarn. I am making a baby blanket that calls for 300g soft acrylic, 4 ply worsted weight yarn. I was wondering if I could substitute this wool yarn for the acrylic- https://www.craftsy.com/knitting/supplies/cascade-220-superwash-yarn/32069
Will it make the same size baby blanket?
Also, when it says, "Weight 100," does that mean 100 grams?
Thanks! I really appreciate the help!
