Joe on his quilt
I knew I could never afford to buy all the different swatches required to make an eye-spy quilt for my son so I scoured ebay until I found someone selling pre-cut squares. Then I just sewed them together in strips, sewed the strips together, added a border, taped the top/batting/backing together on the floor and pinned.
I sewed in the ditch to attach it all together and then my oldest son Ethan picked out a binding from the local store. That was when I had the most trouble... so close to being finished and having never attached a binding before I rushed it and goofed in a few spots. Total material cost was only around $15 including shipping from the ebay seller so it was really economical. Here is a link to a search on ebay showing how nice and frugal it can be to get squares if anyone wants to make one themselves...
Just search ebay for spy quilt squares if you would like to make something similar, there are quite a few people still selling economical bundles of squares...
I made this a few years ago and haven't made a quilt since, only because sewing became difficult due to hand/wrist injuries but it was definitely a fun and easy quilt to make and we still play with it today. It is great for killing time and learning... "Joe, can you find a square with a pink fish? How many fish are in the square?"
