These are not difficult. They only need drying time. I used paper scraps, and bits of ribbon, nothing I didn't already have. The one thing I used that made it really easy was that red glasseine backed double sided tape. It is nice and aggressive in its sticky-ness, so can be used with confidence for this sort of thing.
I bought a set of 3 heart shape cutters. Most likely from a £1 shop, but I honestly can't remember....they've been knocking about for too long. They just about qualify as metal, they at least have a folded top edge to stop you wincing every time you put pressure on them to cut cookie dough or pastry. I used my Cropadile to cut a pair of holes in each one, about half a centimetre apart. First things first, huh. Don't do this if you don't want them to be hanging decorations. Waste of effort.
Choose scrapbook paper or card or hand made paper or stamped and decorated stock or.....whatever you like (it's easier if it's non-fraying) to 'line' each heart. Draw round it..hold the pencil against the metal and the larger heart shape it creates will be enough to snip lines to make folding easier. Cut out and snip.
Now, put the strong tape all around the'sharp' edge of the cutter on the outside. Place this on the cut out paper heart shape with apparently frilled edge and fold the cut pieces up to stick to the tape. Simple. Now it looks really ugly, so put another layer of tape over this and stick on a length of lovely ribbon..the ends of the ribbon should meet tidily in the top V of the heart. Now, run glitter glue around the inside edges of each heart. You can see, I used different colours. When it's dry, you can thread the hearts. Flood em with some UTEE and arty stuff...put lovely pictures in them and have them as tree ornaments....
or you can get horribly involved and decide to make it a bit more of a single decoration....(or, put another way..I don't know where to stop, so I didn't...)
I threaded each heart onto the same ribbon and used buttons to divide them to make it all a bit more rigid. Be patient and cut the ribbon end to a really fine point to make threading easier...and yes, expect to keep cutting it, so use a longer piece than you think...
I actually put a spot of glue behind the two nested hearts in the end, I didn't like them being a bit loose inside one another. You might like that though, and it will be fine. I'll still be talking to you and the world will continue to turn. So then I only had to add interest to one heart really, so I die cut a sweet birdy and a branch (Memory Box and Joy, respectively) and used Glossy Accents to stick it to the thin cutter top edges. And then I used Glossy Accents again, to coat the branch and the bird and then added a sprinkling of Glamour Dust. Because I could...and the recipient likes a bit of bling. Honestly, allow for drying time of the glitter glue, and the longest part was the ribbon threading. You could cheerfully make more than one set at a time and in total only spend about half an hour on each. Nice, huh. It's why I like paper crafting. Results, quick gratification. Works for me.
Have a lovely weekend. And if you make cutter ornaments....please let us see them!
