Hi there. Just building this for our garden.
Having an issue with the arms. The 28 1/2” cut seems to be an inch too short for the frame and to get the 25 1/2” support in also.
As 25 1/2”+ 2”x 2 for both legs is 29 1/2”. Does this make sense? Has anyone else had this issue please?

You may have figured it out by now. A 2 X 4 board is not actually 2 inches depth. It's 1 1/2 inches. So, the two 1/2 inch differences account for the 1 inch you are asking about.

The best way to learn woodworking that I would strongly recommend is to have something like a plan. There are many advantages to doing so that includes:

No wastage of time trying to come up with designs that you aren't sure that they will make an appeal to people or your clients.
Plan you will help you come up with a functional idea that will be acceptable for human use.
Plans will give you an easier leeway to performing tasks in a more elaborate way that will take you from beginner to expert level.
Plans will also give you the technical view of things that projects to your imagination the kind of designs that you would like to come with.
And lastly, Once you get a hang out of the plans then you are able to work on your own imagination and creativity as you now understand the basics of doing things.
Remember that the key to having a successful woodworking experience is to bring out the business side of it even though it has to be your passion or drive. You have to think of it as a business that brings profit and therefore you have to think of whom you shall sell your creation to so as to bring a sense of appreciation if you know what I mean. Therefore you need to at least put in a little cash for what you have passion for and what you believe in. Nothing comes easily without a price. I would recommend you to read this article for a better start and take action on the same.In this teds woodworking review we will discuss the on how to join and see great results from this program.

Hi Ana, I notice a lot of the time in the project you’re drilling into the end grain. Does this have much impact on how robust the whole project is? Would it be better to use pocket holes?

Nice project. I still have to sand and stain. I changed the 2x4 backrest and added another 2x4. In the process of getting cushions. Thank you!

I have been looking the net for relax seat plans. I love the manner in which you don't go all moviestar planet app on us and bring it down to nuts and bolts. I want to do this. Much obliged! Love your blog.

Looks nice and I'm planning to build it, and probably the sectional and table as well as soon as I get done with some things that I "must do" before I get to the "want to do" list. I was curious why you used regular wood screws on the butt joints, screwing into end grain, when you so often talk about pocket screws in that kind of application. I'd appreciate your insight.
