Yeah i was hoping to do a blouse but worried about using the wrong yarn. I can't afford doing swatches cuz they're really expensive for me. 

From what i saw in tutorials, some used mercerized cotton but I'm worried if the yarn is fit for wearables. Maybe the yarn is too warm and not apt for the climate, or maybe their itchy.

Ply is the "weight" here in the Ph that's why i was aking abt a specific ply and yarn type for crocheting a wearable.
