This pattern is adaptable. The blanket can be made in virtually any yarn and you can continue to grow it as big as you want it.
Approximate yardage for 2 common sizes and weights:
For DK or #3 weight yarn you will need approximately 1200 yards for a 40” baby blanket and 2000 yards for a 60” throw-sized blanket.

For Worsted or #4 weight yarn you will need approximately 1000 yards for a 40” baby blanket and 2400 yards for a 60” throw-sized

Hooks: test crocheters have found that we needed a slightly larger hook than we would normally use to avoid curling. Most worked the #3 weight with an H or 5 mm hook, and the worsted with a K or 6.5 mm hook.
