I have read over the guidelines for commercial posts, and I believe I fall within the guidelines.
I am making a wood whistle case for sale, follow the link to see more:
Now, you are probably wondering, a case for wooden whistles, or a case for whistles made of wood? The mystery builds…
Lucky me, lucky me that one’s mine soon!

Way to go, Lark! If I had eight whistles (and hadn’t been vaccinated against WhOA) I’d definitely order one. It looks great and must be a lot of work. Hopefully you have a woodburning set and can burn a little lark symbol into each one.

Lark, that’s a great whistle case! I visited the other areas of your site, and I love the corner knicknack shelf you have up… best to you in your wooden endeavors!!

Hey thats looks super duper. I was too lazy to measure some of my whistles, so what is the largest key you case could hold. This is my 100th post i think. Yeah

Ooooooh! That looks wonderfully like something my whistles would like (I think they would like that ever so much better than their current arrangement of rolling around on my desk, except for the wooden one which sleeps in a tupperware on my desk). Not now, but one of these days someday hopefully I’ll be e-mailing you about one of those. So keep making them for a long time, k? They look great!
