What do you use a pouch for?

• DS puts his handphone
• DS also uses one as his pencil case. He prefers the flat zippered type with zip on the side. He has also requested for another using a fighter jet fabric. I'll put this up when it's ready.
• DD puts her DS along with the earpieces but she's been asking me to make another one which has a separate compartment to put the earpieces
• DD has a round one for her shuffle with the earpiece coming out from a small slot just where the zip ends. This is one of the few that I sew totally by hand.
• I put my keys in one that's shaped like a quadrant. It has a key ring attached to a short internal strap that lets me swing the keys out when I need to use them or back in and zipped up when I don't. It also has a D-ring and strap so it's easy to carry when we go out for a bit. I prefer keys to be enclosed so that it doesn't snag on stuff in my bag.
• I'm currently using a Noah Ark's wristlet with a centre divider that has 3 pockets for cards. Some of the stuff I put inside are: pen, stirrer (DS gave me), about 20 cards, cash, coins, receipts, vouchers etc. I can pack lots inside one wristlet :-)
• I also use a strap as a keychain.
