@schurter may I recommend you upload those as pictures versus attachments? It allows us to flip through them without having to download them.
As for the stain, I haven’t used that Verathane before? Have you used it successfully on that plywood? I only ask because Pine is not the easiest to stain evenly. I have had very good luck with General Finishes Gel Stain on pine before. You can usually only buy it at stores that specialize in woodworking (ie they aren’t sold in big box stores). It is high grade stuff and a little goes a long way. Anyway, it is just a suggestion if you have not used the Verathane and know it works well with this material. I don’t even know if General FInishes has a color you like.
