Home Centre aims at making every visit to its store a treat for the whole family. My comments: I have researched several different types of manufactured board to see which one I think I should use for my product. I have decided to use Medium Density Fibreboard because the boards are smooth, strong and extremely resistant to warping.

Its layered structure makes fixing to the edges difficult. MDF is a board used industrially for the production of furniture, especially shelves and cupboards.

Plywood is made from thin layers of wood glued together at 90 degrees to each other. This makes plywood very strong as it cannot split along the grain like solid timber. If waterproof glue is used the plywood can be used in damp or even wet conditions. Chipboard is made from softwood chips glued together.

It is used to make kitchen worktops and carcases and is a very cheap material. It can be laminated with a melamine layer to give it a decorative and hardwearing finish. Blockboard is made from pieces of softwood in a sandwich with a thin layer of wood at the top and bottom.

It is used to make strong shelves. Hardboard is mainly used in furniture making usually as a back to a shelving unit or cupboard. It is strong and hard because it is made out of exploded wood fibres that have been highly compressed. Manufactured Boards Cotton floss is the most common embroidery thread. It is a thread made of mercerized cotton, composed of six strands that are only loosely twisted together and easily separable.

While there are many manufacturers, the two most-commonly used and oldest brands are DMC and Anchor, both of which have been manufacturing embroidery floss since the 19th century. Other materials used are pearl or perle cotton, Danish flower thread, silk and rayon. Different wool threads, metallic threads or other novelty threads may also be used. The blanket stitch is another easy stitch that effectively provides an edging to materials as well as securing the ends together.

This stitch is ideal for most natural and synthetic materials. The running stitch or straight stitch is the basic stitch in hand- sewing and embroidery and most other forms of sewing are based on this. The stitch involves passing the needle in and out of the fabric either to sew pieces of cloth together or to create designs. An embroidered quilt using the running stitch. An example of the blanket stitch used for edging. The cross stitch is one of the oldest forms of embroidery and is still extremely popular.

It is a simple X-shaped stitch used in a tiled format to create intricate, detailed pictures on cloth. Cross stitch requires fabric that has an even weave that is easy to count. Stitching is done by counting threads in each direction, thereby ensuring that the stitch is uniform in size and appearance.

The colour of thread is the variant used to create the design. My comments: I will be using the running stitch and the blanket stitch to make my removable boxes, playmat and pocket panel. I will not be using the cross stitch as I do not have any pictures that could be made using the cross stitch on my product. Natural Wood Fitting: Materials such as pine can be drilled and screws can be passed through these holes. This gives a cheap and effective knock-down joint. The screws are countersunk into the joint. Rigid Joints: These are moulded in plastic which make them strong.

Screws pass through the four holes which hold the sides at each corner firmly together. A bolt passes through the first fitting and into the second. As the bolt is tightened it draws the two fittings together. This provides a very strong knock down joint and can be easily dismantled using a screwdriver. CAM Lock: The disk fits into a recess in one side of the a cabinet. It rotates by inserting a screwdriver into the slot in its side.

The shaft is screwed into the second side of the cabinet. The collar of the shaft is passed through the hole in the second slot in the disk. When the disk rotates the shaft is locked in position. This keeps both sides of the cabinet locked together. Dowel Joint: A dowel joint is a butt joint reinforced with wooden pegs. It is often used instead of the tenon joint if cost is a consideration in the assembly of work. Dowel holes must be a perfect 90 degrees to the face of the work or the dowel will twist when it is assembled.

It is a neat, strong joint however,drilling accurate holes can be difficult. Weight Target Market Materials Durability Aesthetics Safety Function Size Cost Specificat ion My product should last at least years and my removable boxes should last at least 2 years if used properly. My product must not have any sharp edges or corners which could injure the consumer. Removable parts of my product will not be heavy or small enough to be swallowed, to prevent injury.

My product will be bright and colourful and will have a smooth finish. I will make sure that all edges are sanded to add to the aesthetic value.

The cost of my product would be approximately Dhs as through my research I found that this would be reasonable for the target buyer as my product has various functions. My product should be able to hold the weight of at least 2 children. It should be able to store a suitable amount of toys.

It should be easy to use for the consumer. My product should be a suitable size for my target age group. I will carry out anthropometric research to finalize my measurements. My boxes should be large enough to hold an average amount of toys but small enough for children to hold. However, it should not be too heavy tas this would make it difficult for customers to move around.

My product will have features that will attract its target audience. It will include bold colours red and blue mainly. My storage bench will incorporate common toys for young children such as an abacus etc. Wood should be sturdy and thick enough so that they do not snap easily.

Main materials used for the mat and boxes should be easy to clean as young children may spill things when using them. A strong material should be used to for the abacus rods so that they are sturdy and do not bend when being used.

I measured cut out each piece I needed using a ruler and cutting knife. I cut out nets of boxes to create the drawers and the space where the drawers are inserted into the whole product. I used the running stitch to create some side pockets made out of felt. I drew out a pirate parrot as it added to my theme as well as made it a product that was suitable for both a little boy or little girl. The telescope at the top of the backboard further adds to the theme.

I then made a play mat that would fold up to the side of the storage bench out of some more felt. I used lots of colours to make it appealing to my target audience. I incorporated numbers and letters as children in my target age group are usually starting to learn. A pirate in the middle of the mat emphasizes the theme.

I asked the Year One teachers if I could measure one boy and one girl to make my results applicable to both genders.

I marked where the 2 partitions would be onto the inside of the both sides of the cabinet 36cm apart. Next, I measured out four pieces of wood 2. I attached the shelves using wood glue and some nails to keep them in place and reinforce the joint. I then attached the side of the cabinet with the space for an abacus to the rest of my product. Subsequently, I measured out the two shelves and cut them out using the fret saw. I applied wood glue to the shelf rests on either side of my cabinet and then attached the shelves.

I made the shelves non removable so that my product would be safe for the consumer. If the shelves were removable, the child may pull them out and injure themselves. Diary of Making 1. I measured out the bottom , the two sides, back and the top of the cabinet on some medium density fibreboard of 12mm thickness. I used a ruler and a tri-square to make sure the corner angles were always 90 degrees.

I then cut the 4 pieces out using a circular saw as the pieces were too large to be cut using a fret saw. I proceeded to then join one side of the cabinet to the bottom. I did this by measuring 12mm into the bottom piece and applying some wood glue. I joined the two pieces and made sure that the edges all met properly.
