Are you asking for quilt ideas?
Or not a quilt?
BTW ... in the future ... if you choose the subject name to be something related to what you are asking, more people are likely to respond.
With the subject of "JanelB", it appears to be a GSO (General Shout Out) ... which many would think you are doing a GSO to JanelB, and would not open the thread!
Hope this helps you!!
What a special milestone for your parents!!
If it's a 70th quilt that you are thinking about ... how about a photo quilt? Gather together pictures of their wedding, and other milestones during the years. Of course, of you and siblings, their grands, GGC and potentially for 70 years I'm thinking there might be GGGC and possibly even GGGGC! Other inclusions might be houses they have lived in, hobbies and special interests.
