We thought long and hard about what to get my mother-in-law for her 70th birthday. In the end, her three sons and their families all bought her different things instead of one big present. However, we also wanted to give her something special together to mark the occasion when we celebrated over afternoon tea.
I came up with the idea of a jar that we could fill with reasons explaining why we loved her, one reason for each year of her life. This isn't particularly original and I have seen it done in different ways before. However, it was simple and inexpensive and she was overjoyed with it. The reasons weren't all incredibly meaningful either; some were light-hearted and funny and others reminded us all of things from childhood, which seemed so small at the time, but are ever so important when you look back on them.
All you need is a jar, some ribbon, a printer, a pencil around which to wrap the strips of paper with each reason on - they curl nicely this way and look better in the jar - and a glue stick. Of course you need to come up with the reasons as well. That was the fun bit. And it's never a bad thing as a daughter-in-law to concentrate on all the reasons why you really do love your mother-in-law!
