Ana~ you inspire me every day. I am planning on getting a nail gun this weekend so that I can start on the many projects I have in mind.

Hey Ana,

Are you thinking of adding plans for the "pull down desk top" that was pictured yesterday with the bookcase? I'd love to make that, just don't know how to do it.

Thanks Kelli! And yes, can't wait to put up the plans for the secretary top. I love this collection, it's so simple and all the pieces build on each other!

Love it! Just referred my brother to your sight because his wife has always wanted him to build something for her for her birthday, they've been married almost 6 years! I told him this is the year with your blog! He is so stoked!

Ana, drawers are intimidating. If you are thinking of doing another video would you please do a feature on adding the slides. I can't wrap my head around how it's done without actually seeing it done. Love your blog, I can't wait to try to build something.

I agree with Beth--I'd love an "Ana tutorial" on how to do drawers & slides. I think many of us would be more willing to tackle projects with drawers with some more of your awesome tips!

I am so inspired by your ability to make all these wonderful things...I passed this site on to my daughter( who asked for an air compressor and nail gun for Christmas) and she is in love with all your stuff!

I think I'm going to try this tomorrow...

From what I understand of the plans, I think the drawer front is going to end up being too short. The opening in the drawing is 11.75" high and the drawer is cut from 10" boards. I would think you'd want the drawer front to measure 11". Is this right, or am I reading things wrong?

What is the 4 ' 1X12 board for? It looks like everything but the bottom of the drawer is cut from 1X10's??

Please advise, because I want to cut the drawers ASAP. The rest if finished...thanks, Leda

Ana - the directions in step 1 say the bottom is 36.5", but the illustration says 37.5". Can you clarify this for me? Thanks.

I am having a horrible time finding slides that will work in for this project. I finally found some on line that are 12" and undermount rated at a decent weight however in the document tab it states that the drawer slide = outside drawer box length. SO I am wondering do I actually need a 14 or 15" slide?!?!?!?!?

I will be having a baby via c-section in 9 days and have purchased on 2 seperate occassions 2 different types of slides (the nearest orange or blue store is 3 hours away) and I really would like to get this prject complete before baby arrives so that I can FINALLY have all my paperwork in an appropriate space. THANKS

Barb, I got 12" Accuride slides from Woodcraft and they work great. I had a hard time with this one too!
Congratulations on your baby!

Thanks!! Those were the ones I was looking at online, I will order today then.

this is the same link to the drawers which is what is pictured above I am looking for the unit the drawers fit it

I have seen 2 ways to attach a drawer bottom: inside the sides, and under the sides.

What are the criteria for choosing one over the other? Which will hold more weight? How do undermount vs sidemount slides influence the choice?

I am planning to combine features of this plan, plus "Eco Office File Base - Made with PureBond Formaldehyde Free Plywood" to make a 'chest of drawers' for the kitchen.
