I came across Mama's Felt Cafe during the first Carnival of Natural Parenting that I participated in and I was hooked immediately. Her stuff is absolutely amazing and exactly what I'm looking for to slowly replace some of the less-desirable toys we have with ones that I can feel proud about and will hopefully last a long time. And if you don't want to make these things yourself, you can always visit her Etsy shop!
When I saw her tutorial for "Squishy Squares," I immediately thought "Well, that looks like something I can do!" She breaks everything down really well so that you know exactly what you are doing and how you are going to do it. Unfortunately, I am incredibly slow and this task took me for.ev.er. OK, it took about two weeks but it still felt like forever. Anyway, I know mine don't look half as good as hers (please check hers out because they're awesome :)), but they are done and the jingle a little. I've watched both Heidi and Piper play with them numerous times since I made them, so it was worth it.
Please note: I was not compensated at all for my opinions here. I wrote everything of my own free will :)
