You can buy a T-Shirt with a pocket on the chest but you never see one with a hoodie style pocket. I thought I'd change that and make one. If someone made an 'ible similar to this, please let me know. Otherwise...
-Fabric for pocket
-Scissors, pins, etc
Cost: High: $10
Time: High: 30 mins
Low: 15 mins
Step 1: Cut Out and Reinforce Pocket
Cut out desired shape of the pocket. I reinforced the parts where you're hands go in just by folding and sewing.
Pic #1: Traced the outline of a pocket on my hoodie
Pic #2: Pocket cut out with seam allowance, sewed the diagonals
Pic #3: Diagonals sewn, bottom, side, top are left to sew onto the shirt
Step 2: Sew on Pocket
The top and sides are sewn from the top(sorry I don't know the right terminology), the bottom sewn inside out(not showing the thread)
Pic #1: Centered the pocket, sort of pinned it, then sewed
Pic #2: Bottom sewn
Pic #3: Sides sewn
Then I folded the top, and sewed
Step 3: Finished
Now you have a snazzy white T-Shirt thats still as casual as a white T-Shirt, only now, with more style. And you have another place to hold very light objects.
