Pulling up tent stakes hasn't really been a problem with me, but others may have some difficulty. I took 16" of 3mm static cord and formed a loop with it; 3mm cord fits the notch of many modern tent (Y and V) stakes and gives you a loop you can fit your whole hand inside to help you pull up the stakes. It weighs 1.8 grams and goes inside the peg bag. Use a bright colour such as the red I used.
Alternatively, you could put the same cord through your tent peg bag but make it a bit longer and use it that way; this may put some stress and wear on the bag however.
Note: some brands of V and Y tent stakes have either a hole (to which you add your own cord) or a hole and cord to help with pulling out the stake but these are long enough for only 1 or 2 fingers. If you carry a SAK with the parcel hook in the middle you can use this as a fuller grip peg puller for these pegs.
