I wanted to decorate my study table so I came up with an idea to make my initial letter "J" with rocket images.So lets get inspiration from our initials.

Supplies

Cardboard
Paper(also printer to print)
Glue Gun And Stick
Word Software
2 Magnets
FeviStick
Patience

Step 1: Making the Letter

First,open word and add a WordArt (style 1) and enter your initial in CAPITAL.

Step 2: Advancing Further in the Letter

Take a screenshot of first screen and crop the excess part.
Take the image and insert it in a new word document.

Step 3: Removing Background

Go to picture format of the picture and remove background.
Only remove inner part of the letter.

Step 4: Adding Rocket Background

Take one rocket background image from internet and insert them in word.Scale them so that they cover the whole page.
Then go to picture format of the letter image >>Wrap Text>>In Front Of Text.

Lastly drag the letter over the rocket image.

Step 5: Completing the Letters

Repeat the same process with other letter but do not forget to flip image vertically.

Step 6: Making Strips

Instead of adding word art, add four rectangles and do the same process of the letters with the strips.You can also take the edge measurement for making the lenght of strips presicely.
