The circuit stickers are much easier to use than standard LEDs, as they make better electrical contact and have the polarity clearly marked( see examples from Camilla's class on Slack Acera Pics). However, they are much more expensive.

The standard LEDs sometimes need to be soldered in to make effective electrical contact, and you need to keep track of the polarity. Also, make sure you have the thicker copper tape, as the thin stuff tears easily and is difficult for novices to manipulate.

Also you should (1) start with the artwork (2)locate where the LEDS are going (3)draw the positive and negative circuit paths to connect them (4) Connect the LEDs.
