Jelly Bookmarks: You will need: Coloured Markers (washable), PVA Glue, and a plastic tub, toothpick, and scissors (optional).
First, you need to colour a dent in the lid of your tub with coloured markers (A rectangular dent is preferable). This craft is mainly about the decoration, so if you make more complex designs, it will take longer, however, if you make simple ones, you can probably make more in the time you have. Once you are done, gradually pour a thick layer of glue on top of the pattern, carefully spreading it around (use a toothpick for this). When the glue is dry, peel it off the tub and optionally trim the edges. Now you have an amazing bookmark!
Rock Painting: You will need: Mod Podge and Acrylic Paint (and a place to collect your rocks).
Collect some medium sized rocks from a nearby park or your garden. Rinse them thoroughly until all the dust and dirt comes off. Now, decorate your rock. Some ideas are: a rainbow, a landscape, colourful patterns (stripes, zigzags, swirls) or you could paint something more memorable, such as you with your family or doing something you really enjoy doing. Once you are done, coat with a layer or two of Mod Podge to seal the paint.
Sprinkles! You will need: Toothpicks, coloured markers, scissors.
This is a really easy craft but it is great for when you are bored! All you have to do is colour the toothpicks, each in one solid colour, and cut them up into little pieces with your scissors. The cutting part can be a bit difficult at times, but if you are struggling then try to use a different pair of scissors.
