Learn Farsi: این پارچه هم زیبا و هم ارزان است.

The structure ham... ham... means 'both... and...'. While you can just say ham zibâ, ham arzân, Farsi speakers often add va (and) before the second ham to make the sentence flow better. It essentially means 'both beautiful and also cheap.'

Can I use this ham... ham... structure for verbs and nouns too?

Yes! In this sentence, it connects two adjectives (zibâ and arzân), but you can use it to connect nouns (like 'both tea and coffee') or verbs (like 'I both work and study'). The pattern remains exactly the same.

How would a native speaker say this sentence in casual conversation?

In everyday spoken Farsi, the formal verb ast (is) is usually shortened to an attached -e sound. So instead of arzân ast, you will hear arzâne. Also, the word va is often pronounced as a quick -o, making the middle part sound like ham zibâ-yo ham arzâne.

If I wanted to say 'these fabrics are both beautiful and cheap', would the word in (this) change?

No, in Farsi, demonstrative words like in (this) and ân (that) never become plural. To say 'these fabrics', you only make the noun plural: in pârche-hâ. The rest of the sentence structure would stay exactly the same.
