From time to time I check out what's new for Muslims on etsy. I learned about etsy after my daughter opened up an online shop there. There are other Muslims too and I'll share some items I found to be interesting.For a newlywed gift check out this. For a baby check out this.For kids this and this. For ladies looking for a Malaysian style hijab check out this. (its made by a non-Malaysian interestingly). More kids stuff here.
For everyone try this.
That's just a taste. Be sure to explore yourself. I usually just type in Muslim or Islam or both. Happy hunting.
