Our home was built in the 1880's, we are in the process of looking for a new home, but until then I'm looking for quick fixes to these small problems that do not involve shelling out much or ANY money!
Here is what I did:
STEP THREE: I then covered the cardboard with the sheet. No cutting, no gluing, nothing but a wrinkled thrift store sheet.
STEP FOUR: Place the covered cardboard piece where you need it, I was lucky and was able to put the two sides behind two book shelves we have on either side of the window.
STEP FIVE: Suggestion, add some of your receiving blanket covered pillows (tutorial here: Homespun With Love: 50 Ways to Reuse Receiving Blankets: No Sewing Machine Pillow Cases, Use # 2)
I may end up making another where there isn't a reason for it, but using felt and making some sort of play board for Patrick when he's older, I'll post it if I do!
