This heart bookmark, designed by the amazing Francesco Guarnieri, is an elegant yet simple bookmark. It would make a great Valentine day's gift I am sure :) 

The design includes a whole lot of pre-creasing followed by collapsing heart into shape. Step 8 in the diagram is the most difficult step I think. But if the mountain and valley folds are followed accurately, this shouldn't be a very difficult task. 

I used 80 gsm paper with little hearts printed on it. Small sized squares work best. The 3-inch square I had used, resulted in a 1.5 inch heart, perfect for a book corner.

The Sham, designed by Mio Tsugawa, is a ball-like modular origami made from 30 units. The modules aren't very complicated to make and the assembly is also fairly easy. The model does not require glue to hold it together, but I did add some, so that it does not fall apart easily.

My model was supposed to be done entirely in purple but then I decided to add a band of modules in another colour. I love this combination of purple and pink. I had used a rectangle of size 6 inches by 3 inches and the resulting ball measured about 12 inches in diameter, a bit too big for my liking.

A note on the paper: I have used handmade paper for this model. This is not the best paper to use, since it does not crease well or hold shapes accurately. Hence the use of glue! But origami paper in the size 4:2 inches should result in an excellent Sham.

A Decahedron is a solid polyhedron with ten plane surfaces. As per the wiki, there are 32300 topologically distinct decahedra!

The decahedron is yet another design from John Montroll's 'A Plethora of Polyhedra in Origami'.  The design is for a decahedron made up of 10 equilateral triangles and is of intermediate difficulty.

The paper that I have used is hand made paper with streaks of gold in it. I found the paper great for folding the model. And I like the end result as well.

The Braided Paper, designed by J C Nolan, is a very beautiful origami to fold. It does require some practise to fold it and one that I had tried when I was just a beginner in origami and failed.. It was quite some time after that that I tried another of J C Nolan's design, Andrea's Rose. Now I finally had enough confidence to give Braided Paper another try. And I did it! It is such a beautiful design that I am thrilled that I finally managed to do it! :)

I loved the paper that I used for this design, the same banana paper that I had used for Floral Top. The paper is crisp and thin but strong and very good for folding this model.

A square of 8 inches are higher would be ideal when trying this design for the first time. Anything smaller would lead to a lot of frustration when making the reverse and pleat-sink folds for the model.

There are quite a number of origami butterflies that have been designed. But there are relatively few origami butterfly bookmarks. And of those few, I think the most beautiful is Grzegorz Bubniak's bookmark.

I have stagnated in my folding these days, haven't really tried new things. So this bookmark made an interesting change. I found the steps to be more complex than what I have attempted so far. But despite that, the instructions were clear enough that I could follow and complete them.

The difficulty level for the bookmark is intermediate, I would say. Moving from step 4 to 5 presented the first challenge for me. Going from Step 9 to 10 was also interesting. I had to closely follow the valley and mountain folds to complete the step. I also needed to figure out how to make a swivel fold.

These baby booties, designed by Katsushi Nosho, are easy to make and look very pretty. They would look lovely as decorations or favours for a baby shower.

The booties are held together by a bow, just like real booties! I made these from 8 inch squares and they turned out to the size of a new born baby's foot! But, don't try it out on a baby though ;)

The booties can also be strung together to form a hanging ornament.

The XYZ Diamonds is another planar origami model, made from 3 intersecting diamonds. The design is by Francis Ow, the well known folder/creator of origami hearts.

Though it looks like there are only 3 planes, joined in the middle as though by magic(!), the planar model is actually made of 6 modules. Accuracy is required in folding the modules, else fitting each unit into the next is almost impossible. The first 4 modules can be fitted in easily. The last 2 are not that easy and this is where accuracy of folds makes a difference.

The model works best with 3 colours and 2 modules of each colour.
