If one of your hobbies is woodworking and one is watching TV in that case that is the perfect opportunity for a project. You can make an entertainment center. It is of course a great idea. Many woodworking plans can be found online or if you prefer you can always get one from your trusted hardware store.
Of course this is not a project that you should take on if you by yourself if you do not have the requisite skill to achieve the job. Make it a team project if you can. There are a a small amount of things that you should have before you start your project apart from the requisite woodworking tools. First you have to get a number of woodworking plans for entertainment centers so that you have a selection to choose from. Then you have to select the space that this entertainment center will be put in and do the measurements. It makes no meaning to build something that you will not be able to fit in the space provided or that will be too small to make much of a statement.
Please do not fail to remember to bear the size of the television in mind. It has to be able to fit with appropriate room to breathe. Remember that as an electrical appliance it radiates a lot of warmth so it needs sufficient space for that heat to dissipate. Also bear in mind what other components you will be putting on this entertainment center so that you have the correct number of shelves and storage areas.
With all of this in hand it is time to sit and look through all the woodworking plans and find one that is appropriate or one that can be suitable modified to suit your purpose! Once you have determind on which design is best then you can go out and get the crucial materials like wood (you can decide if you want to use plywood or something hardier), wood screws, edge banding, wood filler etc.
When you have all the vital it is time to use your woodworking plan and build that entertainment center. Just remember that whatever you build should fit it with the rest of the furniture in the room. Also remember that you should leave an adequate amount of space if doable for equipment upgrades. After all you will want to use this piece of furniture for a extended time. It will be the show piece of your skill as a carpenter.
