If ahinsa is wrong in Jainism and we should have sattvic food , then we should also avoid leather and any animal derived cloth or accessories

You are thinking in the right direction.

In Jainism:

• Ahimsa (non‑violence) is not only about food, it applies to all our choices – clothes, accessories, business, travel, entertainment, etc.
• Sāttvik / ahimsak food (pure vegetarian without eggs, and ideally without root vegetables, honey, etc.) is one very important part, but not the only part.

Leather, silk and animal‑derived items

From the view of Jain dharma:

• Leather belts, shoes, wallets, bags, watch straps = products of killing animals, so they clearly go against ahimsa and should be avoided as far as possible.
• Silk (from boiling silkworms), fur, wool from killed animals, bones, ivory, etc. are also himsa‑based and not in line with Jain principles.
• Many traditional and modern Jain guidelines explicitly say:

“Avoid leather and animal‑based material” in: - clothes, - āsan (seat for pooja/jaap), - temple decor, - pratikraman/paushadh dress, etc. ( jainknowledge.com)

So yes, if we accept that killing animals for food is wrong, then killing them for shoes or bags is also wrong – sometimes even more unnecessary.

Then why do many Jains still use leather?

Because Jain dharma is very practical and gradual:

1. Different levels of vows

- Sadhus/Sādhvīs take mahāvrat – very strict, so they completely avoid such things. - Shravaks/Shravikās (laypeople) take aṇuvrat (small vows) – they are expected to reduce and gradually give up violent products as much as possible in their situation.

1. Step‑by‑step practice

- First focus on clear himsa: non‑veg, eggs, alcohol, honey, leather in puja/mandir, etc. - Then gradually remove leather from daily life: shoes, belts, bags, car seats, couches, etc. - Sometimes people are dependent on old items or have limited options; Jainism encourages continuous improvement, not guilt or hypocrisy.

A balanced Jain approach for you

If you want to follow Jain ahimsa more fully, you can:

1. Food

- Stay pure vegetarian (no eggs), avoid obvious himsa items (meat, fish, egg, etc.). - Try to move towards Jain āhār: no root vegetables on certain days or regularly, no honey, etc.

1. Clothing & accessories

- Choose cotton, khadi, linen, plant‑based fabrics. - Avoid/leaving leather step by step: - next shoes: buy non‑leather, - next wallet/belt/watch strap: buy non‑leather, - avoid gifting leather to others. - Avoid silk, fur, wool from killed animals; prefer non‑violent or plant‑based alternatives.

1. Pūjā and dharmik use

- For āsan, mandir decor, pratikraman clothes, etc., never use leather or animal‑derived items. ( jainknowledge.com)

This way your life slowly becomes more ahimsak, sāttvik and aligned with Jain values.
