Welcome,from a stormy Inverness-shire.You have been given good advice in the threads above.The one thing I would add is this.Don't get too wound up about how old a tartan is,they were all new once and many are not as old as you might think.The Welsh tartan may be only,perhaps,30 years old.So what?The most important thing is to get the tartan that your husband will be happy to wear and with a bit of luck it will be one that you really like too.Good luck to you both and have fun.
