If i need more yarn for a project and the shelf is empty can i order from the store?

As long as it is still orderable from the warehouse, yes... they order for the store once a week. They can write you a raincheck (special order)...

Yes

Either in store order or online. Either way it can be mailed directly to your house

Yes they can also check other local stores for you.

Yes, you can place a special order for the amount you need at the store. If there are no backorders, you should receive it in a week or so. Having the SKU #, name of yarn and color would be helpful but someone can assist you with that. Keep in mind dye lots may differ slightly. Hope this was helpful.

I think you can but do double check...give them a call first..
